First off, Kai is an outstanding host. He is very flexible, polite, extremely helpful, and provides great ingredients in his kitchen. The kitchen facilities and amenities are really great. The bed is also comfortable and there are plenty of places to hang clothes and lay suitcases on the floor.
The apartment is on the ground floor, so even if you keep the metal shutters closed at night, and the inner windows open to have air circulation in the apartment, the noise on the street is very loud. There is a street perpendicular to the one the flat is on that has a lot of great bars and restaurants but this is also the source of the noise.We didn't really get a good nights sleep because there were just loud noises off and on all night.
The flat is perpendicular to a street that has great restaurants and also some grocery stores and other markets so this was a big plus. Kai recommended some good restaurants on that street and then we discovered some others that were just excellent. He gave us a list of recommended places to try in Paris and other basic information that was really helpful.
The flat is also conveniently located to the Voltaire metro stop. If you want to go to any of the touristy places like the Louvre for instance it is at least 30 minutes away.
The flat is perfect for one person. But not as comfortable for two people. My husband is over 6'2" and 200lbs and the shower was too small for him. There was only a 5 x 7 mirror in the bathroom and it was difficult for me to do my hair and makeup just with that and there was no sink counter to set things on.
Overall the flat is a good value for a place to stay in Paris and Kai is an awesome host.
