The apartment is of course very well situated in the heart of Montmartre with easy access to the Abesses, Anvers, and Barbès-Rochouchart metro stations, meaning that getting around Paris is easy. The host was very attentive and always responded to my messages in a prompt and helpful manner. The place is very small but you should expect this in Paris; it has plenty of light, which is a plus. I found the fold-out bed (firm mattress) quite comfortable during my one-month stay.
The kitchen has the basics you need to cook (but no microwave), and the wifi works well. Check-in was easy: you retrieve the key from a mini-mart down the street. (I can’t say for sure, but I did wonder if this process would have been complicated for those who don’t speak French, as I do not believe the shopkeeper speaks English).
The only problem I had during my stay was that there was a pretty strong, bad odor in the bathroom, coming from the drain in the shower; it smelled bad enough to make the whole apartment smell like sewage. After I told the host, the building’s landlord (a very nice gentleman) came by and cleaned the drains, yet this did not solve the problem. The landlord told me that other units in the building have the same problem, and that the property management company would send a plumber, but at the time of my departure this still had not happened. Hopefully this issue is quickly resolved, because it was bad enough to diminish the quality of my stay, and I don’t consider myself particularly picky or sensitive to this sort of thing normally.
