We loved our stay at Rae and Jarrod's place. Their house is beautiful and has been updated with modern amenities. The room was spacious and clean and the AC, great. The main bathroom is large, clean, and nicely laid out. We had no problem at all sharing it with the other guests there. Rae was very responsive and helpful to any questions or needs. Rae and Jarrod live in their main part of the house and keep to themselves. You will likely not interact with either unless you need to. We did meet Jarrod going out for an errand and he was very friendly and hoped our stay was comfortable and enjoyable, which it definitely was.
The location is also excellent, with great restaurants right across Mass. Ave and a nice shopping center at Porter Square, a five minute walk up Mass. Ave.
Bottom line is that we highly recommend Rae and Jarrod's place and it will be the first place we look for should we return to Boston/Cambridge.
