This being my first AirBnB stay, and a last minute booking at that, I can say this was an amazing find! (Especially on Easter/marathon weekend) This private studio is great for one or two people and is not lacking in really anything.
The bed is extremely comfortable, the towels and robes are 4* hotel quality, the pillows are varied (as in firmness) and plentiful... I didn't want to leave the bed. The kitchen and bathroom are standard fair with basic necessities, good water pressure, and very hot water. A nice couch, small kitchen table, desk, and dresser fill out the rest of the space perfectly. The building is relatively quiet, with laundry on site if you need as well.
The location is great with being right between Porter and Harvard Squares. A short walk to the red line, and Cambridge Street with various shops, restaurants, and anything you could really need.
The host, Cinzia, is on top of it, kind, and very responsive. E.g. The coffee pot had a hidden crack causing a leak, replaced within a few hours. Overall no complaints. Highly recommend!
