We had a great time at Hilary's. The apartment is located in Cambridge, in a charming building, close to the train and is very convenient for exploring Boston and Cambridge. We had interesting chats with Hilary during our short stay there and she felt more like an old friend than someone we just met. We shared the bathroom with her and her daughter but it was all very seamless. Hilary was communicative both in terms of logistics and at putting us at ease in the shared space. The apartment is on the 3rd floor (in case you have trouble with stairs). Thanks Hilary!
