I see some negative reviews with Harvard Ave Realty, but my experience was with one agent in particular, Dan Patzelt. Dan showed us a place we unfortunately weren’t too happy with once we saw the size, but we went back to his office after at 8PM and he sat with us for over an hour going through listing by listing to find something for us. He was candid regarding location, landlords, price points, etc. In the end, we found something in Brookline that was a great deal though another agency, but Dan was still in contact with us.
He sent us an email asking how the search was going and once we mentioned finding a place, not only did he wish us well but he actually gave us a contact to reach out for to rent parking!
If you’re looking for a place in Brighton/Allston, reach out to him, I swear he knows everyone in the area.
