Alain’s place, as others have said, is ideal for the solo traveler. I stayed one full week and had no issues with space or amenities. There is even a mini fridge for those interested in cooking some of their meals. The location is beyond amazing, and everything people say about Montmartre feeling like a village still is correct. The buildings are lower rise and the streets more quaint. Alain has a bunch of maps and guide books handy and he took the time to sit down with me and explain the public transport, as I had never been to Paris before. He was also speedy with his replies when I asked for a bakery recommendation.
TL;DR
Yes, I recommend staying here and experiencing this little slice of Montmartre, which is itself a very unique slice of Paris.
