1. The location is excellent. Very close to metro, close enough to Eiffel Tower 2. Communication with host is also excellent 3. There is a smell but it is quite normal in old Paris building 3. Elevator does not work but it is also quite normal in Paris. If you have several carriers, it could be quite challenging. 4. Sofa bed has quite bumping noisy. I am fine as single traveller but if you are a couple, it could be a problem. 5. There are enough kitchen cookers but no hot water maker for tea. 6. There is a washing machine but I failed to use. If would be better if there are some explanations in the room, how to use clothes and dish washing machines.
