Sonya's villa is really nice and spacious, the beds are huge and comfy, kitchen has pretty much every appliance you need but there weren't a lot of kitchen tools, only the most basic. Sadly we found some ants in one of the kitchen cabinets but nothing major. The bathroom was spacious, especially the shower. During our stay we often heard noise from the neighbors above us, but I guess that's to be expected.
Public transportation is also close, less than 10 minutes walking, that lets you reach SF Bay area. There's also a small supermarket not too far from the villa.
Communication with Sonya was great and she always replied quickly.
We really enjoyed our stay at Sonya's place and would go there again.
