The thoughtful touches (complimentary coffee, cereal, oatmeal, clearly labeled storage), great communication (instructions, parking understanding, timing) and outstanding location (Bus, Rail, blue Bike, cafes) helped make my stay fantastic. I have only Airbnb's in non-urban areas, not in a larger city area, so I had very little to base my experience on. I was impressed. I ended up just parking my car and didn't miss it once I settled in. I would happily rebook here without hesitation.
I stayed in the "Alpha" bedroom (just me) while another person was staying in the next door "Omega" bedroom. There was almost zero sound from the neighboring room, and I was not at all affected by the common wall. There is a shared bathroom that was clean, well lit, spacious and functional. I clean soft towels, the host offered really useful services (rides to the airport, laundry services, etc.) that I didn't need, but I can sure appreciate how those touches would have been fantastic. The private bedroom and public spaces were all warm and comfortable. There's an electronic lock on the door as well as a deadbolt that requires a key, which was great. The closet was plenty roomy and has an iron and ironing board available to use. The hangers were not the cheap ones I've grown to hate. The little things :-)
The kitchen area would have functional for light cooking had I needed it. I tend to not take the time to grocery shop and cook on my trips. Still, I noticed a far more well-stocked kitchen than what I've become used to seeing in listings.
The most notable element of the space I was immensely appreciative of was the functionality of the bedroom. There is a comfortable bed, sofa, desk, office chair and ample lighting in the bedroom. I felt like I had a great little suite to sleep in, enough room on the sofa to sit and go through my bag easily, and a clean, flat, level desk for working on my laptop with some papers next to it.
For those not too familiar with the Boston area, from this location it's an easy 10'ish minute walk Harvard is, MIT is a 10'ish minute bike ride, and downtown Boston is 15-20 min in a car or 25'ish min on a Blue Bike. I wanted to see more of the area, so I never tried the rail service. I ended up using Blue Bike multiple times a day and it was great, including riding in and through Boston. I wish my home city (San Francisco) was so easy to get around.
