The apartment is very nicely decorated and comfortable, and also very quiet, so no problems to sleep or anything like that. The whole building is modern, with a very convenient supermarket at the piazza and an enormous park just in front. The bus stops right outside the building, so no problem at all to move around the city.
Together with this, Stephen has been the perfect host, kind and attentive all the time, and very helpful in all the queries we had.
This was our first time to London, but certainly not the last. We still have many things to do and places to visit, so we will return, that's for sure. And when we do, our first option to stay there will be Stephen's apartment.
So, I would definitely recommend this place to anyone going to London.
