Our family - two adults and our 7 year old son - travelled to London last week and stayed in this apartment. We arrived around 9pm, which was after the standard check-in time. That was no problem, however, they have a small safe outside the apartment where they put the keys. This worked perfectly. The apartment was nice and clean, with a very well-equipped kitchen and even tea and coffee to get us started. Our son slept on the couch in the living-room / kitchen area, which was absolutely fine. We slept in the bedroom, the bed and the matrace were comfortable. You have to keep in mind that the apartment is facing a busy main road, the walls and windows are pretty thin, so it's louder than I'm used to. People might need to use earplugs to find some sleep. If one wanted to write something bad, there was some mould in the shower, but not to bad that it kept us from showering. We didn't see the staff personally, but received a friendly phone call asking us if everything was alright. Would definitely come again.
