We had a very nice week-end in London, maria’s lodging is very well located : you’ll just have to walk during 20-30 minutes to buckingham palace and only 10-15 minutes to the underground at Victoria station.
The room is very clean and The street is so quiet. Maria is a nice and welcoming host and you’ll have all what you need (blankets, towels...)
If I come back in London, I’ll ask again to Maria without hesitation !
