This was all in all a subpar stay for us. The communication was great, and Paul and his housekeeper, Jen, were extremely accommodating of our shifting arrival time. We didn't meet Paul, but Jen was absolutely lovely. There is water and beer and unlimited Baby Bel cheeses available in the fridge, although we didn't really take much. The room itself was fairly clean, and the bathroom was spotless. The location is fantastic, a very quiet but well-connected neighborhood.
Otherwise, the place gives off what I can only describe as weird hostel vibes. It was clear to us from the moment we first sat on it that the mattress should have been replaced years ago. We slept terribly and woke up with worse and worse aches and pains each day that we were there. We had also chosen to book an Airbnb instead of a hotel to grant us access to a kitchen, but while the countertops were clean and clear, the kitchen was otherwise absolutely filthy - the oven was unusable until another guest spent an hour cleaning it out, and the drawers and cupboards were so full of filth we felt we had to wash all the dishes before using them in addition to after. Also, there was a cracked tupperware with rotting meat in the fridge that stank up the fridge so much I threw out the entire thing - I assume it was in there long enough that no one would come to claim it. There was also a guy who would sometimes just... sleep on the couch, which is fine, but a bit odd. We came back late one night and were chatting in the kitchen before we heard a snore and realized he was there. Also, a lot of things were just slightly broken - the shower head was slightly disconnected and sprayed water straight out whenever you opened the door, the dishwasher didn't work, there was a fancy mirror that had a button for a light but wouldn't turn on, etc.
If you are under 25 and don't experience any sort of back pain, this is probably a great stay for you. Otherwise, a similarly-priced hotel might be a better bet if you want to be able to enjoy your sightseeing without bodily discomfort.
