The flat is beautiful and quite new. The building is still under renovation but when this will be finished it will be really great. The localization is really perfect, near the center and easy to find.
We didn't met Sarah but email exchanges were clear and simple. The person who checked us in was really friendly.
This flat would have been so cool if there were no enormous construction just across the street in front of the bedroom window. The construction was under progress from 6am to 20pm (including the Sunday we were there). In addition, no curtains on the bedroom window, and also work in progress in the flat just under us... So I can say that we really didn't enjoyed our night there.
Be sure that the construction is finished. Then it will be surely wonderful.
