I loved the building location, and the style & cleanliness of the unit. The building is located about 3 blocks from Prudential Center, near public transit, shops, and tourist spots, in a quiet, safe-looking neighborhood.
The unit was comfortably warm, and heats up very quickly if you want it warmer. There were functional windows which allowed for letting in fresh air. In addition to the listed bathroom amenities, there were also toothpaste packets and mouth wash. The bed might be spacious enough for 2 people if they were around 5' and thin and do not move too much. The sofa is a little over 5' long.
Some things to be aware of is that there is no onsite staff to enforce the house rules and office hours are from 9am to 10 pm. Also, I came back one day to find the unit unlocked. That was rather disconcerting.
The kitchenette was not as functional as I thought it would be. Useful additions would be sharp knives and a stove that doesn't make the room lights flicker. There are many nearby restaurants though, and a Trader Joe's for microwaveable meals.
This is a good place for a short-term stay as long as you have the good luck of having considerate neighbors or don't care about noise. I was not so lucky. My first night felt like staying in a frat house, with loud voices, thudding music, and a lot of door slamming. Another night, around 2 am, the couple next door decided to spend about an hour taking turns crying out and making weird noises.
