Stayed here for 4 days for work. Checkin is seamless (simple lockbox) and host is out of hair but if you need him, Im sure he'll be there but lucky I didn't have any concerns. If you have mobility issues, there is no elevator so its two sets of stairs. Place is clean, bed is comfortable but wouldn't be great for couple unless you like cuddling all night. I stayed on my own.
My biggest issue was the bathroom was on the small side but its clean and comes with towels. The couch was also abit uncomfortable too but I didn't mind it much, I was still able to kick back after long day at work.
The place is close to busy strip, and 15 minutes walk to city centre. Good location and it feels safe unlike many areas. Might seem sketchy at first but Boston is old and ppl that live there are all professionals or families it seemed.
