Joann's place is a gem, and easily one of the best airbnbs I have ever stayed in! Her home is spacious, sparkling clean, and stocked with just about every amenity you would need for your trip. The bed was also incredibly comfortable, which was exactly what I needed after an 18-hour journey!
Joann's sister was also kind enough to come down in person during the check-in to show me around the house, and both of them were very responsive. The place was also walking distance to supermarkets, Target, and several other stores, and a short walk from the CalTrain station. I would definitely stay here again when I'm back in Mountain View!
