Max And Billie’s apartment provided a great experience for us. It was nice and cozy, had an excellent temperature (it was around 0 degrees and snowing outside) and in a good location.
The apartment gives a very good feeling overall. However, due to it being old, there are some parts that don't "feel" squeaky clean (while I'm sure they were), such as the bathroom and the building's hallways. Also, there were quite a few loud noises floating around (mainly from the apartment's and building's pluming, as well as other guests' activities - didn't have good sound-proofing).
Kudos to Billie for accommodating our luggage in his office for a few hours before we checked in and after we checked out.
All in all, I would positively choose it again.
