Mark is a very nice and understanding host. The airbnb is in a beautiful neighborhood in a very cute house. We picked this airbnb because all of the reviews were great! Our experience was a little disappointing. First, the airbnb was not properly cleaned for our arrival. The shower floor was covered in small black hairs, and used toiletries were scattered around the bathroom. We were then worried about the bedding, so we found an extra pair of sheets in the closet and changed them ourselves, just to feel better. Mark was out of town, but was very understanding. I believe his sister was staying upstairs while we were there, and she tried to clean it when we were out for the day. She also left us a bottle of wine :) On the last night we were there, it was getting close to dinner time and we could hear that more people were accumulating upstairs, which was fine. No biggy, people have parties. Anyways, I had just gotten out of the shower and this random girl walked into our place! (There is an interior door that connects upstairs to downstairs.) We couldn't lock it from our side. The random girl and I were both freaked out. Thankfully, I had clothes on! So weirded out at this point. After dinner we got back to the airbnb around 11 after spending the evening with our friends who just moved to SF. The party upstairs was going strong, which is cool, it's still normal party hours. We could hear everything going on. Finally, at 3:45AM, after moving from bedroom to living room, and back to bedroom to see if either was a quieter space to sleep, my husband went outside and upstairs to see if they could do anything to be quieter. We had to be at the airport at 7AM. They understood and started getting ready for bed. They vacuumed, moved every piece of furniture around, and made pallets. I promise, we could hear EVERY. SINGLE. THING. After all of these mishaps, we were so glad to leave this airbnb. I think we had a random bad experience. Mark did refund our last night, which was very generous. Other than that, San Francisco was great!
