We loved our stay here, the apartment is beautifully presented, spacious and in an excellent location for exploring Paris. We are a family of to adults and 3 children (6, 10 and 12).
The only reason we couldn't give this 5 stars is the lack of air conditioning. Our stay in August wasn't as warm as it has been recently, but we couldn't get the apartment below 27 degrees at night, which made sleeping difficult. There are fans provided in every room though, so this may not be a big deal for everyone. It would put us off staying here during the hotter months of the year though.
