I stayed in Armand's apartment for two weeks (originally about 10 days then I added a few) for both work and pleasure. The apartment can fit 2-3 people. The couch is fine as well. The apartment is in a great locations - Belleville is really lovely. Lots of different cultures, cheap food, bars, etc. It's up and coming but not too loud. The apartment has a lot of natural light which is great and I really liked the design as well. The apartment is clean. Armand has a lot of books on art and culture (though I did not read them myself and not sure if they are available for guests). He is very nice, responded quickly, and was easy going. Belleville and Buttes Chaumont park are very closeby and peaceful. Belleville is two stops from Republique. I've been to Paris many times so I definitely suggest this area if you'd like to have a local-type of stay.
