We have just returned from a six night stay here. I should start with a few things that they DON'T tell you: Firstly, as you will see from my photos, this hotel is situated at the TOP of a very high cliff. The funicular railway runs from 9am until 7pm - after that the only way back up is (a) walk!!! (b) taxi (if you can find one!!) or (c) take your life in your hands up a VERY dodgy path which is unlit and the steps are uneven to put it mildly.
Secondly - beware the photos that are shown here on Trip Advisor and Expedia show a mix of photos from this hotel and it's sister hotel the Grand (which is situated down in the town). The lovely renaissance looking rooms, palm tree lined pool and bar with squishy looking sofas are NOT Punta San Martino. If you are looking for elegance - try the Grand, Punta San Martino is more reminiscent of hotels you'll find on the Costa Brava etc.
Thirdly - there is no bar as such. There is a room referred to as a bar, but it's not.
Fourthly - the main 'semi-olympic' pool is open to the public, who seem to have priority over paying guests when it comes to choosing where to sit. On the Sunday we were there, we were 'corralled' onto a sun terrace (see photo) and were not allowed to sit around the pool. On other days we could sit round the pool on sunbeds that weren't displaying a reserved tag. Also, if you are not a proficient swimmer, be warned that the pools are both around 10 - 12ft deep (not that there are any markers to show you).
Fifthly - there is no hotel information in the room i.e. breakfast times, pool times. Interestingly enough, nothing was explained to us at time of checking in either- we had to find out by trial and error.
Finally (phew!) - be very aware that if you happen to end up with a room that has a connecting door to the next room, unlike every other hotel I have stayed in that has had them, there is only one door (normally there is one in each room forming a sort of 'air lock'). You can hear EVERYTHING (and I mean EVERYTHING) that is going on next door!!! (Which also means they can hear you - not that our neighbours took the hint!).

I would rate this hotel as high end 3 star - it is very quiet and remote from the hubub of the town, but it comes at a price (or a plus whichever way you look at it) I now have thigh muscles of steel thanks to the nightly ascent of the hill!!

I've given it a few brick bats - so I feel I owe it some flowers: It is very clean, we had clean bedding every day (maids start very early on the room cleaning - so stick a DND sign on the door if you want a lie in). Breakfast was a very leisurely affair, out on the terrace. Buffet as is the norm these days and very continental ( no sausage, eggs and bacon) - plenty of croissants, meats, fruit, cereals etc. The views from the hotel are breathtaking (as long as you don't get a room that has an oak tree in front of the balcony - see photo). Balconies are very generous, with sun loungers - but not particularly private.

Highly recommend this hotel. We arrived here after having spent a night in Pegli in the Castello Miramare which was really hopeless in comparison, despite being only slightly cheaper.

We were pleasantly surprised by the spaciousness of the room we had, it really was huge and as far as I know it was just a standard room. It had a bright blue feature wall and furniture and fittings which gave the room a lot of character and a good vibe in general. The window overlooked the sea.

The bathroom was clean and reasonably modern. There was a bath with a shower in it and the bathroom was also spacious. There was also a door separating the bedroom from the corridor which gives access to the bathroom and this helped to reduce noise from other guests in the hall.

The bed was really big - as is often the case it was made of two single beds stuck together to form a queen/king size bed, but it was very comfortable nonetheless.

The position of the hotel is quite isolated, not super central, but this makes it very quiet for a peaceful night's sleep. (I'm a light sleeper and I slept very well in this hotel.) It's best if you have a car though as it's quite a walk up a hill to reach the hotel by foot from the center of Arenzano. The hotel has a free car park and we always found a spot in it.

The staff were friendly and efficient at checking us in and out.

Breakfast is superb especially by Italian hotel standards. It is served in a room that overlooks both the pool and the sea. You can also have breakfast outside on the terrace to really make the most of the stunning view. There was a large buffet with fresh fruit, pastries/croissants, cereal, yoghurt, cold meats, boiled eggs, biscuits, cakes etc.... and fruit juices. Hot drinks are ordered from the waiting staff and are very good.

You can even hire bikes from the hotel's affiliated partner in town.

We can't wait to find the time to come back to this hotel - 1 night was just not enough.

Excellent service, there was a beautiful view from a very comfortable room. The food was fantastic. The staff were very friendly and helpful. The hotel is situated on a cliff and has wonderful views and and a way down to the beach. It also has a swimming pool.

Stayed here for 1 night on way to France and was sadly disapointed. Booked a superior room with balcony which had a sea view you could see thru the trees but no furniture to sit on. Bedroom great size and nice childrens bed but no guest information whatsoever in room meaning several trips to reception to ask general info re breakfast and bar etc from a not very helpful receptionist. No bar to speak of after 7pm unless you ate in the restaurant although it had a lovely bar it was closed. Discovered the mini bar by accident on returning to our room at 10pm but as there was no price list did not want to risk it.This is not what I would consider a 4* Hotel. However the pools were lovely and the breakfast nice and plentifull. Not great value for money but maybe Italy is just more expensive.
