The flat is really cool, clean and the host and co hosts are really friendly, may be the only negative thing in the flat is the 5th floor with out a lift, so if you do not have a luggage it is perfect and if you have the host and co host are really friendly and they are offreing the help anytime.
They are really awsome.
The view for the river is amazing, it is like 15 min walking from the centre.
