I overall enjoyed my stay at the apartment. The location was very good. It is a very large space for Paris. The wifi is fast. The AC is cold. It is very very quiet being on the courtyard, but also a bit darker. The neighborhood is really nice and there are plenty of supermarket, restaurants, transport, etc. close by. The place is just overall chill and relaxing.
While I really enjoyed the stay - I think the cleanliness could be greatly improved and the flexibility or just changing how guests check in could make the stay better. The host was relatively inflexible about a check in time and the person I had to wait for was late.
Some other reviews do not like the shower arrangement, but I think this would only be bothersome if someone had to enter the bedroom while one was showering. I was traveling alone, but I agree with some other reviews that a stay with 6 people would be too many.
