Valentino (Tony) is an extremely engaged and hospitable host! We initially had a bit of trouble finding the actual place as the building isn't clearly marked or numbered, but once we got in touch with Tony via AirBnB/text (to which he responded almost instantly), everything went smoothly. He directed us on where to stop to unload our bags, then directed us to a spot to park overnight for $12 as the local street parking is $50-$60/night. Be prepared to walk 5 or so blocks for that parking, however. We were greeted with a glass of wine and a quiet place to relax after a long day of traveling.
The place was very clean and quaint, nothing fancy but everything was totally sufficient and comfortable. After long days of experiencing the delicious restaurants Tony recommended, it was nice to feel like we had a place to come "home" to rest compared to a conventional hotel room.
Absolutely ask Tony for food and sightseeing recommendations, our meals were one of the highlights of our trip and we would've had no idea about the places we got to dine at without Antonio and his city connections!
Next time we come back to SF we will absolutely be staying with Tony again -- highly recommended!
