I stayed at Jean-Luc's place for almost a month. The apartment is beautiful. Everything is brand new. If you love to cook the kitchen is amazing. Full size fridge, giant gas range, and dishwasher. He supplies all the dishes and cookware needed. There is a brand new washer and dryer on the second floor.
The neighborhood has lots of restaurants and stores within walking distance, most within the same block.
Jean Luc is very attentive if you need anything he takes care of it within the same day. Usually within a couple of hours depending on the problem.
I would gladly stay again when in Boston.
