Xavier is very good with communicating and giving instructions on how to access the room (very detailed). He was on hand although we never got to meet because of conflicting schedules and travel. However, I felt comfortable that I could ask him about anything I needed.
The internet works well; there is adequate lighting through the foyer, up the stairs, in the room. This is comforting particularly if you arrive after dark. It is a secure apartment and quiet neighbourhood and I met some friendly neighbours in the same building.
The space is small. If you have luggage, it is not ideal as there is no room for a suitcase and the elevate does not reach the floor of the room, so you may struggle with lugging suitcases up to the floor. As long as you are not finicky about showering in the evening and using the kitchen sink as a bathroom sink, it is suitable for you. Suitable for short stays, not long stays. Extremely accessible to everything - you can walk or take the metro and get around fairly easily. Major and minor shopping areas; tour busses within walking distance. Lots of places to eat on the same street, just around the corner, and within the area. Taxi also within walking distance. I was comfortable walking around by myself and did not struggle to get around considering it was my first time in Paris.
As a host, I would recommend Xavier for his friendliness and easy communication. He was always accommodating and patient and I did not struggle with my booking at all.
