This is definitely the best place to stay in London if you're traveling alone!
Gillian and Graham are wonderful, caring, and thoughtful people. The breakfast is delicious, the room is very clean and cozy with study desks and a fridge, and the best very comfortable. The bathroom is very spacious and clean and is entirely for your use. The patio is very lovely and there's a nice communal garden.
The neighborhood is very quiet, safe, convenient, and the closest tube station is only 5 minutes away.
BEST place to stay, work, and travel! I would definitely recommend their place.
