The unit pictured was a single bed but the room I received was a bunk bed. The bathroom is located across the hall from the bedroom and the bedroom is in a shared 'suite' with other private bedrooms. There is a common area. There are three layers to get to the bedroom: keycard main entry, key access suite entry, and key access private room. Safety is not an issue though there were times when the suite entry was left unlocked by other guests. There is housekeeping daily which I did not know or expect or want. After the first day, the housekeeping walked into my room as I was asleep and woke me up, I verbally requested no more housekeeping as there was no opt out sign. The same thing happened the next morning. The walls were thin and I could hear people playing table tennis. It wasn't until I was ironing my clothes that I realized it was from the basement below me. There is a safe in the room but I couldn't get it to work after three attempts following the directions. The host and staff were nice in my brief interactions but I value my privacy and found the experience uncomfortable with the housekeeping situation. If you're a light sleeper then you would not do well here. I could hear others staying in the building and it kept me awake. If you're looking for a cheaper place near MIT (it's across from MIT museum), near a grocery store (one on the same street just 300 feet or so from the door), and down the road from Harvard (about a mile walk up green street) then this will work. Bring earplugs.
