Liked: Cleanliness, staff & service, amenities, property conditions & facilities
The room was modest but clean and had everything we needed. It’s perfect for a quick overnight or even a few nights. There’s a fridge in the room so we brought what we needed for breakfast in the morning. There’s a microwave in the lobby and coffees and teas. We stayed while our granddaughter was at Boston Children’s Hospital. Although close in distance it still took us almost 30 minutes to get there with traffic but that seems normal for the area. Overall it was a good stay. The front desk people were very warm, friendly and professional.

It was a great place to stay for the night. Clean and professional. The only complaint is that the bathroom door didn’t close completely and the heater was really loud.

Felt safe saying alone with my daughter. Was close to a lot of places we had to visit in Boston. Staff was friendly and helpful. Room was clean and cleaning available upon request as we stayed a week. Fridge in room saved us money and time. There was a microwave available in the lobby for travelers use. Amazing value for cost.
