This place was adequate for our needs. Although it is compact and located in a basement, they made good use of the space to separate it into several areas.
If you are tall, taking a shower will be tricky. There's a nice tub, but the bathroom has a very low ceiling. I am 5'6" and my head nearly touched the ceiling when I stepped up and into the tub to take a shower. I don't know how to describe the shower head. I've never seen one like it and it sprays in every direction, so it's hard to actually wash your hair or your body. The ceiling fan above the shower didn't have a cover so make sure your head and hair don't get pulled in! Yes, the bathroom ceiling is really that low.
After coming down the stairs, the hallway is damp and musty, but it's not as bad once you step in to the AirbNb. The nature of the carpeting plus a basement with no airflow did set off my son's allergies, but it wasn't too bad. A fan or additional air filter in the bedrooms would definitely help the lack of airflow due to the place having zero windows.
The neighborhood was awesome, and we were able to get parking on a side street nearby. I recommend going up to the Bernal Heights Hill and watching the sunset and taking pictures on the swing! It looks like you're soaring over the world.
San Fran is tight on space, so I think the place was fair for the price. Side note--- a mani/pedi next door is $50, not the $20 mentioned in the listing. I did not see or hear from the owner, but I did meet the cleaner who came a little early, and he was very kind and polite.
