The description of the apartment is very precise, there's a bedroom with a king size mattress, very well kept kitchen and bathroom , a good living room and a small balcony.
You can reach the center in about 20 minutes using the public transport. And a large market within 15 min walking.
Tanya gave us all the information necessary to have a great time in London.
The house seems to have several personal belongings, it could be a good idea to just highlight what is available to be used and not. In the end Tanya was very kind and available to support in any queries we had.
