We have just used Punthill Manhattan and it did not live up to all its description. Yes, living room spacious and airy and pleasant. But the bathroom was tired and needs updating; the shower was over a very narrow bath and very cramped and rather dangerous for getting in/out. The bedding was strange: the bottom unfitted sheet was too small for the bed and rode up, the blankets were some cheap sort of material and looked rather worn. Not what we expected fro other experiences of city apartments.

As the name applies this is an apartment hotel in the middle of Melbourne CBD and the pricing are accordingly not low.
House keeping seems a little slow. I arrived at 1300, I was told room will only be ready at 1400 and it was almost 1500 before it was ready. Most high class hotel I came across lately try to accommodate early comers, especially if very close to official check in hour (1400).
Location is excellent, 5-10 min walk from federation square, lots of restaurants and cafes close by and a small commercial center with a cinema on the other side of the road from the hotel.
The apartment/room is very nice. Done in a "New-York" loft sort of way (hence the name "Manhattan") . My room which was a one bed room apartment had a large living room with sofa, eating table and an "office corner", kitchen (quite large actually), with all appliances and utilities, a separate bed-room and a big bathroom with a shower/bath and a washer/drier. The ceiling is bare concrete as befits a loft. Wi-Fi is very expensive (18$ a day) if you use it.
The gym is very small and basic and maintenance of equipment is not top notch. pool is nothing more than a puddle. If you need a jog the royal botanical gardens have a 4-5K running track surrounding them which is much nicer.
This is a nice place, I believe if able to afford it an excellent place for business men in town for a week or two but good for tourists as well.

We had a 2 bedroom/2 bathroom apartment for 3 girls, we were very happy with location, short walk to trams, etc. Great for exploring melbourne on foot. Recommend.

Stayed here for 10 nights for a work trip. Convenient to a few places for breakfast. Walking distance to great places (Chinatown, Myers etc) and near the free City Circle trams. Apartment itself is very spacious, had laundry/dryer facilities. Kitchen was great, just felt like living in a city apartment. Didn't use the pool and gym facility. Had a room at 3rd level, so at least felt open looking out the window - not much of a view but that's ok. Great it has a decent internet service $3/hr instead of some places where they charge you $20/day flat rate. Had wifi and cable internet. Staff is friendly when looking for advice or booking shuttle to airport. Would be nice to have the TV in the room too. Bed was nice and soft.
