Overall, I had a great time at Gema's house. The room is at the very top of the house, so you have to walk up two flights of stairs, which is not hard, but I am tall. Once I got the hang of that, the room was great. Gema even asked me if I wanted something to eat. She is super sweet.
My only issue is communication. Once I arrived in Boston, I texted her, called her, and called her backline. Nobody picked up. I decided to take the T train and call her once I got close to the house. Once I was at her house, It took me about 10-15 minutes to get a hold of her. Things happens, so it is not a big deal. If I were to stay again, I would leave a voice message for her.
Overall, communication was not that big of a deal. Her place is really close to MIT, she offered a number of restaurants to eat, and changed the sheet.
100% would reccomend.
