I recommend this as a good place to stay in Boston. It was perfect for a four-day business trip. It has a small kitchen, a small table, a desk with outlets and decent WiFi.
It is a nice 2nd-floor walk-up studio apartment with big windows in a great neighborhood for restaurants and cafes, and within walking distance to the financial district.
I happened to arrive with the first hot weather of the year and the unit was still winterized and very warm. The host was responsive to my concerns and remedied the problem by installing the A/C promptly.
