We had a great 2 months living with Leonid in San Francisco. Best aspects are the super new, stylish bathroom, the very quiet neighborhood with security guard and the lake nearby.
Leonid is very friendly and respectful, he works from home a lot. You can have great conversations with him if you want to and he respects the privacy of the guests.
The room is on the top floor and features a bed, lamp, chairs and large closet but no desk (you can use the one in the kitchen if you want). In some aspects, the house interior is a bit sparse as there would be place for an additional little bedside table, laundry basket, bin, ... but that's not a large hindrance. You have access to the kitchen to cook small meals, as the fridge is tiny. The private bathroom is just amazing with a walk-in shower and very nice finish - you will love it. Overall, Leonids place is very clean. I would recommend it to anyone who is looking for a quiet place to stay in and doesn't mind the very small drawbacks I mentioned.
