My two roommates and I had a great experience with Maurika. Seems like the one-star reviews concern other realtors, so I'd recommend asking for her when you call! My two roommates and I got a really cute and affordable 2-bed with a roof deck through Harvard Ave.
Maurika was very flexible with timing, and organized both a viewing and a lease signing after work hours, making it really convenient for us. She put us in contact with the current tenants, and we were able to negotiate over taking some of their furniture. She also helped us negotiate with the landlord about having an extra roommate when he originally only wanted to rent to two people. Additionally, she gave us her phone number and was happy to take calls outside of work hours. Maurika was able to meet us right at the apartment to get the keys instead of the office.
The only issues we had were that we only got one set of keys, which was inconvenient, and we weren't entirely solid about move-in time until the day before. It was a Sept. 1 move, though, so that's how those things go. Anyway, that's why Harvard Ave is 4, not 5, stars.
Overall a great experience! Would definitely work with Maurika again for housing in Brookline/Allston.
