Viviane was an amazing hostess. She was quick to respond when we had issues getting into the place (push hard at the door inside the courtyard while it is beeping and when you think you’re done turning to unlock your studio door, turn some more). When we accidentally blew a circuit and had shower draining issues, she also replied quickly, giving us detailed instructions on how to fix it.
Keep in mind there is a long circling staircase all the way up (4th floor, with ground floor being Floor 0) which is disclosed in the listing. The place is very small but has everything you really need. The couch bed was not very comfortable but clean. The building is very old but clean. The shower is also tiny and drains very slowly so we had to keep turning off the water while showering. The fridge also likes to start vibrating/humming loudly every few hours for a long time but we figure out if you tug on the door a bit, it makes it a lot quieter.
We felt extremely safe with all the codes and keys to get in. I have never seen a door with that many locks and because it is near several embassies, there are police at all hours of the day around the area. It is also close to a bus and train station, making it very easy to get around.
