Amazing stay! The flat is clean and comfortable, and it has everything you need. The room is very cozy and probably bigger than most places you'll find at a similar location. Lera is a lovely woman with lots of interesting stories and ideas. I absolutely loved my stay and would recommend it without any reservation!
P.S. If you're from a northern country, you'd probably find the heating level in London, generally speaking, underwhelming. So a hoodie or sweater indoors is advised.
