We spent 11 nights in Clémence's apartment and were happy to have booked it. The apartment is exactly as in the pictures and very central to public transport (bus, metro (Marmaray), ferry), the sea (to do nice walks in the evening), supermarkets/cafes and the mall. Clémence was a great host and had our initial problems with the internet fixed the following day. The apartment was clean when we moved into it. However, there was a bit of a moldy/fusty smell in the apartment that lingered with us for our entire stay. I think this is due to the fact that it is a basement apartment. On the whole, we were very satisfied and would book the apartment again at any time. Üsküdar is a lovely place with very kind and helpful citizens. We thank Clémence very much for offering us her place and make it a great trip!
P.s. keep the windows closed if you are not a big fan of cats, because they sneak into the apartment from time to time when something is open.
