Thomas was very friendly and welcoming at check-in. His apartment feels spacious considering its size, it's simple and stylish and is in an excellent location. I would recommend it if you're looking for somewhere in a young, lively, trendy area. The location is right in the middle of things but the apartment itself is at the back of a courtyard behind the busy road and so still feels private and quiet. As well as hip bars and places to eat there are some very good specialist wine bars nearby.
If you're going to be in Paris for an extended stay it's probably worth bearing in mind that the bed is a sofa bed and so might not be the most comfortable for a longer period. (There were also works going on at the building, which was a shame as it was noisy in the mornings, but that is presumably only temporary!) We really enjoyed our stay -- thank you very much Thomas.
