The host appears to be a rental/leasing company. They were timely and professional and included all of the information I needed to find the location and enter the building/room. It was very nice not to have to worry about meeting up with someone and I could travel at my own schedule. The location was very safe and quiet for a main street in Boston. Ammenities were excellent and it was a nice touch to find oatmeal, coffee and juices in the kitchen. The apartment was very clean,comfortable and well kept. As a single female traveler I felt very safe in the apartment. The ability to use a roof deck in this location was an exceptional highlight of the experience.
