It's a really nice room, with a low bed (almost like a futon) and plenty of hanging space. There's also a very useful shared kitchen with cooker/oven/microwave and fridge/freezer and space to eat breakfast. The area is fine - plenty of shops and cafes on Ocean Avenue about 5-10 minutes walk away. Pho Ha Tien is a popular Vietnamese noodle and sandwich shop, and there's a Whole Foods store if you want to pick up a soup or salad about 5 minutes' further away.

If you're coming from the airport alone, you can take the BART to Balboa Park and then a #29 bus to the top of the road (it's a steep downhill), or the Muni (tram) line K along Ocean Avenue. If there's two of you, it may be as easy to grab a taxi or ride share such as Uber.

I was working in the downtown area for a week, and had borrowed a colleague's spare bicycle which I was able to keep in Jennifer's garage. It's about 40-45 minutes ride in the morning (check Google for the best cycling streets), and rather longer coming home in the evening as it's more uphill (but not impossibly so). But you can also put your bike onto BART - each train has space for many bikes - and this is a great option in the later evening once it's dark.

The bathroom can get congested as the toilet is shared with the shower/bath, and hopefully you'll have considerate Guests in the other room (there are two double rooms). The only problem I had during my stay was on arrival - I didn't have a mobile phone that worked on a US network, and Jennifer wasn't at home when I arrived. I managed to log into the wifi standing outside her house (check you have the password in advance!) and send a message to her through the AirBnB system. But it might be better to try and message her from the airport.

Jennifer is a friendly yet unobtrusive host, and on the one occasion I met Josh he was very helpful, too.
