Charming flat in a beautiful area. Was a two stories up with no elevator so be prepared to carry your luggage up the stairs. The tube that we used the most (Earl's Court) was about a 7-10 minute walk from the home.
Be prepared for no A/C. Normal in London but definitely can get hot at night and we were there end of September. We even slept with the windows cracked in the bedrooms to have some air circulation and left all the windows open during the day.
Wifi is not great. We had 4 people and struggled with getting 1 or 2 people on wifi without the system saying it was full. Supposedy there were other options to choose from for wifi to login on but they never showed up as network options on anyone's phone.
All in all it was a good stay with some hiccups along the way but we enjoyed our time.
