This is a great apartment. I would definitely stay here again.
Pros: Affordably priced, nicely renovated, clean, well stocked kitchen, comfy king bed, very welcoming and responsive hosts (NOT some anonymous company), easy walking distance to the subway, quiet neighborhood, fast wifi.
Cons: Like most Boston apartments, it's on the smaller side. The ceilings are low. It's the ground floor apartment, and the upstairs neighbors stomped around a bit.
All in all, I would stay again! Great place.
