Perfect location, right next to two underground stations, walking distance from Hyde Park and restaurants and pub. We had a minor hiccup at check-in but Giulia was very quick to respond and to sort it out. The flat is super spacious, comfortable and decorated with style. The only downside (and has nothing to do with the host), is that the flat is located between two youth hostels, so there was a lot of loitering, and littering, especially at night. Fortunately, the bedroom is at the back of the flat so that did not disturb our sleep.
Overall, we're satisfied with our stay!
