We, a group of three colleagues, stayed in Robert's and Shelly's house for three and a half weeks. We had an extended visit in Santa Clara due to a business trip and after 1.5 weeks in a hotel we decided to switch to an Airbnb. That and also deciding for specifically their house was exactly the right thing to do as Robert's and Shelly's house was not only very cozy and calm but also comfortable and clean. We found everything as promised and felt very welcome.
A special note has to be done for their very good service here: We arrived in the evening and noticed some problems with the drainage. Despite that it was a holiday and also out of common business hours, Shelly was easily reachable via phone and even managed to get us to another place for one night while they fixed the problem!
Overall, we had a very good experience and can definitely recommend Robert and Shelly as a host!
