We are a family with children, reserve a 3 BR Apt 7 wks in advance for GBP450 for 19 nights. They took the whole dues in advance.
When we arrived we found it was a real big cheat ,, pictures were so illusive, they don't reflect the actual thing which was not worth half the price.
The entrance was very small that it can hardly take 4 persons standing and the old junk small elevator that can take only 2 persons, it scared my children and they used the stairs to go to the 6th floor. The receiption staff were nice but can't solve any matter , they are remotely controled from some where.
What can I say ,,,, the only thing was nice was the kitchen and one ot the 2 bathrooms, other wise rooms were very small and the curtains are mostly broken and old.
We tried to change the place but left with no chilce since we paid in advance although we negotiated to that they charge us for 4 or 5 nights but no way.
In conclusion : I don't recommecd this place despite its closeness to any one that wants to enjoy their stay >>> It is not worth half the listed price.
Very very disappointed.

I stayed here for a couple months this year and feel the same about Fountain House as many of the other reviewers. It was nice having a large flat right at the top of Hyde Park and next to the Tube (which was closed almost every single weekend I stayed there! Very frustrating!!), but I don't think the apartment was anything to write home about. Two of the bedrooms were facing Lancaster Terrace and got all the noise from the street, but the back bedroom was quiet and stayed dark in the morning.
The kitchen is more than adequate with all the appliances you could need, plus plates, pot/pans, silverware, etc. There was also a washer/dryer combo which took FOREVER, but better than nothing I suppose. The living room area was ok; had a flat screen tv on the wall, DVD player, two couches, coffee table, and a dining table with 4 chairs. The cleaning crew came three days during the week and always did a very thorough job. I did not find the front desk staff to be overly friendly, but it's not a hotel and they are not a concierge, so I won't give them too hard of a time on this review.
A couple nights there were drunk people screaming in the hallways (knocked on my door one time) and the intercom system to the front entrance is annoying as people rang my room at random hours. I would recommend the Fountain House to all people in all situations, but it could be a good fit depending on your circumstances. The location is excellent. Hope the pictures give you a good idea of what the flat is reaally like.

Our stay at the Fountain House appears to mirror those of a number of other reviews I have read. We were traveling with two young children (8yrs & 4yrs) and therefore the location being so close to the park and also the tube station was great. The size was good and the bathroom and kitchen quite new. The carpet had a number of burns where someone had dropped an iron while doing their clothes, some curtains & blinds were broken and the couch had a lot of stains. This was not in itself terouble as we understand that you expect some of these things in an apartment used by numerous different people, but we did come back one day to find that the covers on the couch and cushions had been removed and replaced by sheets. I am guessing to have them cleaned, but they were gone for nearly three days and no one said a word to us. A lady did actually come in to check on the broken curtains and noticed that the couch covers were missing and said she would check into it. We never heard back and therefore I can't say the service was very good at all, but the cleaning was done once while we were there for 5 nights and was done very well.

As our experience appears to mirror those of others who have placed reviews on 'Trip Advisor', I don't think anything is changing very quickly and therefore cannot recommend this apartment as I have previously done with others.

This apartment is not a bad value for the price, relative to other London hotels/apartments. The location is very convenient (literally across the street from Hyde Park and Lancaster Gate tube stop). The kitchen and bath are nicely updated. However, the carpet and the couches were in VERY poor condition. The couches are literally threadbare. Very disappointing considering that we were told this was a refurbished apartment. The service was acceptable, if you keep in mind that this is a service apartment, not a hotel. For example, we had plumbing problems on the weekend that could not be attended to until Monday. The housecleaning staff was very nice and cooperative with our schedule.
