Had an amazing stay at this apartment! Great location in the North End! It was very walkable to explore the neighborhood and close to T stations for going a bit further out. Great area for restaurants and sight seeing.
I did a long term stay (35 nights) and the desk space in a nook in one of the bedrooms made it possible to work remotely really well. There was also a strong internet connection for working, no issues staying connected. The apartment is small as noted but it was also comfortable (I was staying by myself).
One note: if you or someone you are traveling with has concerns on stairs, this unit is on the second floor and there is a flight and a half of steep-ish steps (there is a half-flight up to the ground apartment). I had no trouble with this but it is worth noting as there is no elevator.
