First, Mario and his assistants were great hosts. Good communication, clear directions, etc.
The location is amazing if you are trying to be near Petco Park or Gaslamp - all walkable. There are a lot of homeless folks sleeping and hanging out in the area. If that bothers you, this isn't the place. Not a safety issue though. Just folks down on their luck or with mental health stuff going on.
The house itself is just OK. You have to walk through the main bedroom and the little bedroom to get to the patio. That's inconvenient if the person in one of those rooms is still asleep when others want to use the patio.
The back bedroom is very, very small. Wide enough for a single bed, a night stand and a path for others to get to the back patio. It is more of a sleeping cube than a bedroom
The beds and pillows are pretty soft, so if you like to sleep firm this isn't for you. Sofa bed not great, but fine if you put it on the floor.
Back patio is really nice. TV is new, big and sharp. Refridge is big. Plenty of space in the kitchen. No dining table which might matter for families.
