The room is located in a good place near Hyde Park. We like walking, so almost didn't use public transport to get to the city center.
The room was clean with a comfortable bed. The kitchen has everything you need if you'd like to cook for yourself.
The apartment has three rooms, so you'll be sharing the bathroom with other guests. In this case, the cleanliness of the bathroom depends on the tidiness of guests.
Even a small noise in other rooms or hall is very well heard. It didn't bother us, mostly because the guests were quite. But it's important to know.
Moshe is very responsive, which is really great: easy check-in and check-out.
Overall, it's a good choice to stay in London.
