Tony and Cathy were the consummate hosts - the guesthouse is a true haven! I made the booking for my parents, who stayed there for two weeks.
The Location: I am biased as I am local to the area, but the location does not get better than this. While tucked away in a quiet, tree lined street, it's a short and enjoyable walk to College Ave. where you can find fantastic restaurants of all kinds (from casual coffee to arguably the best Italian you can get in the Bay Area). Also walkable to BART, our primary public transportation train system.
The guesthouse: very clean and charming. Many homes in the area have a lot of rich history and Airbnbs can be a bit "vintage", but the guesthouse is newly built while still maintaining the character of the neighborhood. It was an incredibly comfortable stay, and the exact right footprint. My parents stayed here during a heatwave (high 90s for a few days) and hardly had the A/C on because of how well insulated the house was - if I ever built a guesthouse, I'll have to ask Tony and Cathy for their blueprint (haha!)!
The amenities: zero complaints here - we had everything we needed.
The communication: kind, prompt, and clear! Check-in was extremely easy, as was checking out.
