Fred was very kind and helpful.
We enjoyed the stay in his flat. The accommodation is one metro station away from Eiffel Tower. So, very central.
Nearby are a lot of restaurants, bars, small bakeries with quite nice stuff.
The flat itself was good. In the bedroom you have a decent sized bed. So enough space for a couple.
One small minus point: there is no shelves or whatsoever for storing our clothes. We stayed one week and we would have wished to have a shelve for our clothes.
Thanks from Dmitrij and Maria!
