You arrive and the first thing that you see are the views over the bay and they're pretty phenomenal. There were 4 of us staying as well as a toddler for a fortnight and there was ample room for all of us. With some small movement of some of the side tables, it was actually very child friendly. The beds in the two bedrooms are very comfortable, though the third (fold-down) bed in the family room was a little less so (although not bad). The view from the master bedroom over the bay was exceptional (especially from the remote control bed). Whilst in the picture it shows some blinds in the bedroom, not all the windows had blinds, this wasn't a major problem (except for getting our toddler to nap in that room during the day).
Apparently the tenants before had left the place in a terrible state and as a result, when we arrived the carpets were still damp from being washed and the whole place felt a little unclean. After emailing with the host and several messages back and forth, they sent round the cleaner (who was very friendly and helpful) who cleaned the cooker, shoe tray, tables, bathrooms, and fridge, vacuumed the rug and the holiday finally felt like it could begin. They also gave us a complimentary bottle of wine.
We also made them aware of an ant problem they had in the upstairs bathroom which ended up escalating with ants everywhere (in the bathroom) and leaving us being able to use only one bathroom (which made it a little difficult with five of us staying). The cleaner bought and left us one lot of ant traps which didn't work and then another lot which did (but which meant we had to put out new bait several times). I know it wasn't the hosts fault but this kind of tarnished the stay us.
The location was good, with easy access (about 15-20 mins drive) into Berkeley and Oakland, and 40-60 mins into San Francisco (depending on the traffic), but you definitely need a car whilst staying here.
We'd definitely visit the Bay Area again, and although this place has wonderful views and nice space, the issues we had mean we're not sure this would be our first choice place to stay next time.
