The location is absolutely unbeatable, and the place is solid.
Positives: It has plenty of space to host 3-5 people, a great view of Dolores Park, and has an incredible sound system built into the ceilings. The kitchen and bathrooms are recently redone, so the place is fairly well-equipped. They are extremely responsive hosts (e.g. we asked for an iron and they brought one within 30 minutes). For a short stay, this place is a clear top choice - we'd recommend it to anyone.
Negatives: For a longer stay (we were there for 8 weeks), we thought it could be improved a bit - though nothing the host couldn't fix. Basically, the kitchen wasn't well stocked (it clearly wasn't stocked for someone to really cook in there), and the furniture is all Ikea and not the most comfortable if you're using it 2-3x/week.
Overall: That said, the location is so good that it kind of makes up for any drawbacks, the hosts are great and we would still gladly stay here again.
