This flat is in a fabulous part of Paris. Plenty of little shops, bars and restaurants in the immediate area. Many of the sights of Paris are within walking distance. Very close to a Metro station (the Metro system is extensive and easy to use). Despite its central location, it's very quiet and I had a great nights sleep on both nights that I stayed.
The room is as you see it in the photo: small. but for a couple of nights it's fine.
The listing says that one room is available, but actually the room below was also let out. With the hosts, that means five people in the flat, but we didn't get in each other's way so it was fine.
The flat is being refurbished and the kitchen and bathroom are temporary. Also, there is no lounge but given the great location it was nice to relax after a day's sightseeing in one of the many local cafes. The flat is on the third floor and the winding stairs are not easy to negotiate with heavy luggage and would not be suitable for anyone who has a mobility problem.
Once finished it will be a beautiful flat, but for now be aware that it's somewhat makeshift and cramped, although fine for a short visit.
Of course, this is all reflected in the price, which for this part of Paris is very good value. I stayed on a Sunday and Monday night, so I didn't see much of Silvia or her partner, although I was given tips on where to go as soon as I arrived, as well as a map which proved to be essential.
