I booked this hotel for a long weekend break based on excellent reviews on this site and wasn't disappointed. Got a very good price on Otel.com (had to request a with breakfast price which wasn't quoted but was very worthwhile). From arrival to departure all expectations were met or exceeded. I requested a high room with a view in advance and this was a good idea: some rooms look onto an internal courtyard whereas we had a panoramic view of London from the 11th floor with the London Eye and Palace of Westminster very close (Room 1102). Room was exceptionally clean and comfortable (I understand the hotel has been open 4 years but it doesn't show). Every member of staff (there were plenty of them) was smiling and so friendly; a manager even showed us the Penthouse Rooms without any pressure to upgrade! Breakfast (full buffet, not just continental) was excellent too.

If I was picky I'd point out that the dining room isn't really big enough but there were plenty of staff clearing all the time and we never had to wait more than a couple of minutes for a table. At the busiest times there can be a wait for a lift from the higher floors but usually it was very quick. Also, there is free Wi-Fi in all rooms but we didn't manage to get it to work (may have been our fault). We had a problem with the safe on the day of departure but an engineer arrived within minutes of calling and was as friendly and polite as all of the staff we met.

There is a small Gym but we didn't use it.

The hotel's location is absolutely perfect for a London break with two tube stations nearby (Waterloo and Westminster), The London Eye and Southbank almost outside the front door and the whole of the west end a within a 20 min walk across the river.

One thing to note: there are two Park Plaza hotels almost adjacent to each other: we weren't the first to try to check in at the Park Plaza Westminster Bridge!

Enjoyed our stay, good breakfast, drop off parking outside is difficult and the one-way system makes it hard to get to on the first attempt. The bar could be bigger, not enough seats. One of the good hotels in London.

Walking distance from Waterloo a very nice hotel with all the service you'd expect from excellent rated place to stay. Had an n excellent studio room, which was in superb condition, the bathroom, which is always an indicator of cleanliness was fantastic, looked new with no hidden mold or damp smells so often encountered in hotels.
Although a London-eye view, you could only see the top of it due to other buildings in the way so not really a selling point and not worth worrying about if you don't get that view.
Slight confusion with wi-fi, Internet connection details were unclear and therefore didn't try to connect my ipad to the wi-fi and they tried to charge a fiver for about 2 mins Internet use via the TV which I didn't realize was chargeable. So, wi-fi or hard wired in room is free, communal area wi-fi chargeable, Internet via TV is chargeable. Waived the fee after I complained.
All in all a lovely hotel, in a great spot for Westminster, South Bank, Tate Modern, St Pauls walks.

It was our second visit to this wonderful modern hotel for my wife and I and we were not disappointed.
Once again we were given excellent customer service, especially so from the friendly and helpful staff at the check in desk. We arrived early and to our delight we were upgraded to a studio room that we could use immediately. Another nice touch was that on learning that we were celebrating a birthday a complementary bottle of wine was left in our room.
The breakfast in this hotel is superb, not only for the modest price but for the excellent service, extensive choice and quality that is provided.
