I traveled with my 16 year old grandson and found the hotel had comfortable accomodations and was close to the Swiss Cottage tube stop and shops and restaurants. I liked being in a neighborhood rather than the center of the city. Part of the joy of visiting London is being able to use public transportation to get all over the city. We enjoyed the London Eye, Victoria and Albert Museum, Science Museum, British Museum and just walking around. Having a friend who lived 3 blocks away was a great plus..

We used the hotel to be located near family members for a party. Otherwise, we'd have stayed in the centre of London - probably at much less expense. I was really annoyed when the room rate came up at £118 - but then added tax - bring it to around £135 - unheard of in my experience in the UK. This didn't even include breakfast.
The room was fine, nice and big with a balcony. However, there was a big gap in the patio door so it would probably be freezing in winter! Pool was fine, although changing rooms located quite a distance from the pool and you have to go down a set of narrow steps with wet feet which isn't an ideal situation, especially for kids. The underground line at Swiss Cottage was closed the weekend we visited for the development work for the olympics, so we had to walk to Finsbury Park - 10 minutes walk, although this did take you past quite a number of good restaurants. Overall, the stay was ok - but I wouldn't pay this much money for this hotel again.

This is a nice hotel in a quiet street a little outside of the Center. For the Underground station is just 5 mins walk, you can reach the very center easily. The rooms are furnished tastefully, the beds are very comfortable and you'll find everything you need.
On our departure day we had a problem with my luggage and the staff of the hotel, especially their manager on duty, did an outstanding job in helping us to sort it out. You'll only really find out about the quality of a hotel and their guest relation when there is a problem to solve, an the staff of this hotel was really top.

My sister and I stayed here on points for 3 nights while visiting London. Hotel is further out of the center of tourist destinations, the closest touristy thing is the London Zoo. However, the hotel is located less than 10 minutes walk from the Swiss Cottage stop on the Jubilee line so getting around wasn't difficult. Hotel room was as expected for a Marriott with comfortable beds. I did have Platinum status, so my sister and I were able to make use of the Executive Lounge for snacks, beverages, light h'or d'oeuvres and breakfast. Hotel staff for the most part were very welcoming...the only person that wasn't so welcoming was the elderly lady who set out the nightly happy hour h'or d'oeuvres in the Executive Lounge...she always seemed suspicious as to whether my sister and I should be in the lounge as we were definitely the youngest looking people who made use of the lounge. She always checked their sign-in book to see if we had signed in whenever we showed up, but never did it to any of the other people who entered the lounge after us. Overall a good hotel, can't say that it's one I'd definitely return to, but it's definitely a hotel I'd use as a "back up" if there isn't a better option available when I'm back in London.
