Alain's place in Montmartre was amazing. I was there for 3 months and it truly felt like home. Alain was very helpful and answered any questions I had. The neighborhood is also quite cozy. The street itself is quiet enough but walking just 5 minutes in 10 different directions you'll find a ton to do. The nearest metro stations are about an 8 minute walk away, but it's quite easy to get around Paris by metro, bus, or Uber (quite cheap). There was also quite a bit of space for a Paris apartment, and all the essentials you need for a short or long-term stay. I would definitely stay here again if I come back to Paris.
