Communication between us and German was good prior to arrival - we were given the entry code and told where we could park. There were some renovations going on outside the house, but this didn't affect us at all.
Positives: This was one of the cheaper properties we found on Airbnb for the SF/Oakland area. For what we paid, this was an okay option for us. It's obviously not that central, but it's easy to drive over to SF and the metro station is a 15-min walk away. There's also a supermarket a few blocks away, parking available outside the property and we felt safe in the neighbourhood.

Negatives: We were disappointed when we arrived to find that the place had not been properly cleaned - there was dust on the floor, the kitchen was dirty, and the bed linen was stained and had holes. As we arrived late the first night we couldn't do anything about this until the next day. However, the next morning I contacted German and explained the problem, and Adam came from upstairs and gave the apartment a thorough clean after we went out, bought in new sheets and left a bottle of wine as a goodwill gesture, and we appreciated this.
We also had problems getting the shower to work. We were told before we arrived that there is a trick to getting it to work, but we struggled with this and had to wait till Adam came down in the morning to show us. Once we saw how to do it, everything was fine and we had enough hot water for all 5 of us to take a shower.
The issues with the cleaning and the shower meant that we were delayed in leaving that day to enjoy our time in San Francisco - but we were grateful that once we had told the hosts about these problems, they responded right away.
This Airbnb is a good option for groups on a budget who don't want to pay SF prices. If there's a problem, the hosts are responsive and will offer a solution.
