If a review was on location alone this studio would get a great review, of course it's not. The most telling sign of a poor experience is that I would never stay in this apartment again.
The photos of this flat are very misleading, it is much smaller than it looks in the pictures, it is also very dingy and dirty. Exposed electrical wires throughout including the bathroom. If you like to sleep after a long day in Paris, this is not the place for you, there is a club underneath your window and the walls are paper thin.
If one of the reasons you would stay here is because of the promise of Wifi, quickly cancel your stay, because you will not be having any. That was a major issue for me and my brother, who do not have French phones so the only way we can contact family and friends is when our phones are connected to wifi, we couldn't look up directions to restaurants or even museum hours. Not that we wanted to spend all day in the flat, but it would have been nice to have a home base where we could plan our next moves.
Since we never met Gilbert, we were never taught the how to operate the outside code for the security door to gain entry into our apartment. Which was a major issue. When we contacted him, he was unhelpful and told us it was either this set of three numbers or this one and that all you need to do is swipe a pass and type one of the sets and we would gain entry. It never worked. When we contacted again at this point begging for a set of clear directions so that we could gain entry we never got them. We had to wait outside for a person to come down and open the door, or after a half hour of trying one of the combinations finally worked, which though we will never know.
I have stayed in other BnB's in other major European cities and have never had a problem, and have four more trips planned in the coming months, this was a major disappointment. If you can find a different place with a different host in the same neighborhood do it. The pictures do not equal the apartment, and the host was certainly no help in making us feel welcome.
