I cannot recommend this flat enough. It is just as described in the listing and is more spacious than I expected. The building is very nice too. The location is great (one half block from the Pompidou Center!)
The responsiveness of the host was always quick, and she was helpful. The information left at the flat was helpful and we took advantage of some of the recommendations.
I have been to Paris many times and I am familiar with the Marais. This flat is exactly what and where I wanted to be this trip. I will book it again when I go back.
