While Brian and Heather were good hosts and the appartement itself was clean and well prepared, the building itself is really awful. Unfortunately, the building is located on a corner of Boston Commons where a lot of druggies hang out. I think this is the case because the entrance is in a cul de sac where there is little through traffic at nighttime. I used one of the parking spots provided by Brian and Heather (it was one of the reason I chose this property) and unfortunately after the first night my car was full of footprints on my hood, windscreen and roof (no major damage though). We stayed 3 nights and when we checked in I was surprised to see that only one of the 3 lifts was working (our rented flat was on the 5th floor - the top floor). On the second day, the 3rd lift broke down and the apartment became a walk-up until after we checked out (I had to do multiple runs to carry our 9 or 10 pieces of luggage down the stairs). The stench of urine in the stairways and lower hallways was truly shocking (though the top floor hallway did not have these bad smells). I recommend that anyone renting this property read the reviews on google of rentals at this same address before committing to renting here (it appears like the entire building consists of apartments for short term rental - every door had similar code based locks).
That said, I would definitely recommend other properties managed by Brian and Heather. The apartment was clean, well furnished and they were extremely responsive (responses within 15mins) and the check-in and check-out procedures were very smooth.
