Gema is lovely and very kind. Things to know: you have to climb steep, narrow steps to get to two of the rooms. The bathroom was shared and one floor down. I didn’t mind going down a flight of stairs and never had to wait to use it. As the bathroom is shared with two other guests you have to be comfortable with sharing and evidence of other people using the same space.
The neighborhood is very quiet and there are restaurants, corner stores, coffee shops in walking distance. It’s a great place to stay if you are visiting MIT and up for a 20 minute walk.
