Alexander's apartment is in a great location, about 5 minutes walk from Ledru Rollin metro stop, or 10 minutes to Bastille. It's surrounded by quirky shops and cafes and there is a fab market around the corner. The apartment is small (as described) but perfectly formed, warm and cosy. I shared the bed happily with my young daughter and my sister slept comfortably on the pull out sofa bed.
There is no TV, so in the evening we enjoyed sitting chilling and looking at Alexander's many amazing coffee table books and chatting over a bottle of wine. The wifi was strong so we were able to look things up and plan the next day in advance. Alexander was a great help to me in planning our trip, answering messages quickly and having prepared a guidebook of his local tips which we loved. We also enjoyed the fun, tongue in cheek notes which had been left around the apartment - including a translation of a cover of a Charlie Hebdo magazine.
The street noise at night is loud, which Alexander has been upfront about - it isn't terrible, just lots of laughing and talking. I mention it only as I brought my earplugs, and future guests might want to bring theirs too. To be clear though, I slept like a log!
