When we first booked, we were a little wary of how few reviews there were, but our experience has been great. Pascal was amazing, het explained everything really well and he answered quickly when we had questions.
We where with five and we all fit easily. The sleep couch is a proper two person mattress that is folded op against the wall, which was a really nice surprise.
The apartment itself is quite small, but that is to be expected in Paris. All amenities were present, including a dishwasher and a washing machine.
You can get to the city centre in about 25 minutes with the metro or bus all in all, though the metro station is a 12 minute walk from the apartment.
All in all, a good experience and a nice appartement for the price point.
