An ideal location with easy access to a variety of public transport. A cozy flat, with a large bed and a nice, separate sitting area. The flat is clean and comfortable, feels newly refurbished, offering a bathroom and shower that feels more like home than a hotel. The sitting area couch lays flat for sleeping. My brother says it was comfortable. The small refrigerator and microwave are handy. Yann is friendly and accommodating, making sure we had easy access and everything we needed. We were constantly on the go, so our only face-to-face meeting with Yann was the morning of our departure, but that is fine with me, as he regularly checked with me via text and email.
I recommend this flat and this host to San Francisco visitors, with or without a car. The area is quiet and safe.
