Staying Jonathan's place was honestly the best choice I made in my trip to Boston. His apartment was very quiet, safe, conveniently located to supermarkets or shops to buy daily stuff, and definitely affordable.
In the loft, you've got nice amenities including water, coffee, snacks, and most importantly, fully personal space! And I have to mention this, I LOVED the shampoo and conditioner in the common bathroom, which was super clean and new.
All the other common space such as kitchen and living room was very nice too.
When I went out to hang out with my friends in downtown and Newbury, I used Lyft and it was not expensive at all every time, so I recommend that more than booking other places that are closer to downtown but more expensive.
Also, Jonathan was so kind and responsible because he's always responded very quick and came help me when I had to take my language to the top of the loft and bring them down.
