It's clean but very expensive for what you get. However, if you NEED a pet friendly place to stay, this is a good choice. The Trolley Barn park is nearby (a normal park, not a dog park), there's a decent amount of room inside the apartment and it's clean. We stayed here while work was being done at place we were renting nearby, and this was one of the few AirBnBs in the area (we looked for places near either our workplaces in Kearny Mesa or where we currently lived in North Park) that allowed pets and had free parking and WiFi. One of our pets does very poorly in boarding (it affects his health) so we usually get a sitter, but since we had to vacate the premises, taking him with us was our only option, so a pet-friendly AirBnb was the best option.
The biggest problems we had were with the bathroom - the bathroom sink didn't drain (took the entire day to drain a half full sink from brushing teeth, washing hands after using the bathroom, and shaving). The shower turns on by pulling very hard on the knob towards you (I am familiar with this type of shower so that wasn't the problem), but the shower has absolutely no temperature control. The knob swings freely once you pull it outwards. However, the water defaulted to lukewarm, eventually warming up to slightly warm with occasional cold spurts so it was tolerable. The provided shampoo, which I used once, made my hair unbearably tacky. I'd advise bringing your own toiletries.
The cookware was also not great (dull knives and the smaller pot was missing a handle), but I honestly don't expect much from an AirBnB kitchen. If you don't plan to cook, the AirBnB is VERY close to the University Heights (Park Ave) or the north end of North Park (30th St). These areas have a LOT of good restaurants and little shops. We were local and not on vacation, so we did not go there (had to use the kitchen), but we are familiar with the area and it's a great place to do some shopping and eating.
The bed was VERY comfortable and clean, I was very satisfied with that. Sometime even staying at nice hotels, my back will hurt after - this was not the case at this AirBnB. We stayed a whole week and my back did not suffer any ill effects. I could also hear footsteps from the upstairs neighbors throughout the day but this wasn't a huge issue for me. There are little heating units in the wall and they are very directional but I found them to be effective. They managed to warm up the room to comfortable levels throughout the day.
I also don't love the fact that you are expected to take out the trash and do the dishes before you leave, considering that we are paying almost $100 in cleaning fees for the stay (not including pet fees). There is no dish drying rack and there is only one dish towel, so we had to use the dish towel to dry the dishes on and used paper towels for everything else. However, I will note that when we arrived, there was no evidence of other pets having stayed there previously (no pet hair, no litter dust), so they are doing a good job cleaning in that regard.
