Mario is an excellent host. I personally didn't get to spent much time sadly to get to know him as well as I wanted to. He is very professional, very knowledgeable, and has a beautiful home. Is very convenient to a lot of places in San Francisco. Is very clean, free WiFi, free Xfinity, there is a fridge, a place to put your clothes in, and a microwave. The shower is great! The bed is one of the most comfortable beds you will ever lay on. The area is very car friendly too. I had no problem finding parking and it was free! This place is much better than a hotel.
