We stayed on the second floor of Yossi's parents' house. There are two bedrooms, in one of which is where the bathroom is located. To access the bathroom, people staying in the second bedroom needs to feel comfortable walking into the first bedroom. There is a sliding screen that tried to separate the sleeping area in the first bedroom from the passage way to the bathroom, but the screen was broken when we came in, so we had to hang a bedding sheet to visually separate the space for privacy.
Otherwise, the beds are comfortable and the space is very clean. The location is close for us driving into downtown and Cambridge. Yossi's parents are welcoming and were able to accommodate our late check-in. Overall our experience at Yossi's place is great.
