Possibly the best location for someone without a car. Right next to the Belmont L station, it's about 3 minutes from out the door to waiting for a train. Surrounded by shopping (Target, small grocery stores), and food/pubs. Many coffee places nearby, one is literally just downstairs. Absolutely recommend staying here, especially for long-term.
It IS loud. The train is right next door and construction is bountiful around this area. I would absolutely bring earplugs or noise-canceling headphones. The construction made it very hard to do online interviews and any audio-based work. This was NOT the fault of the hosts but is a reality of the location.
Overall, it was an excellent stay. The space is very large and open, the bed is comfortable, and there's a lot of storage. I will say that the hosts seem very strict (may be due to building policy) on guests and what you can do with the space. Thanks for hosting me!
