The location is great, orange line is right downstairs, green line and red line is a 2 mins walk. A lot of things are in walkable distance, China town, shopping area, Boston commons, etc. fortunately, during my stay there, there wasn’t outside noise which I read in other comments.
It’s like a youth hostel style, so do expect to share bathrooms with other tenants here. Depending on how clean your neighbors are, the common areas (kitchen and bathrooms) can be clean or not very clean, but the common areas were in general pretty clean during my stay. If there is anything that bothers you in terms of the cleanliness, do not hesitate to contact the landlord.
Communication was great! They are very spontaneous, they did a little screening with me before confirming my reservation, they send out information that you need to know before/during/after your stay once confirmed. They are eager to help, in their information doc they mentioned that they did not do baggage storage before check in, but my friend and I needed it, so I asked for it, and they actually did that with an extra fee. They also checked in with me during my stay, I reported the unwashed dishes, which I should have done the first day I got there. They sent out an email to all the tenants on my floor about the issue, and most of the dishes were gone the next day.
The room size is great for two people, bed sizes were great (I think queen size lower level bunker and the upper bunker is a inch or two narrower).
Overall, it was a great stay at this place, I would recommend this place for a sightseeing kind of visit.
