The apartment is really nice and very stylish. You really feel like in a true Bostonian place.
The area is also very nice, with a lot of restaurants, cafes, etc. It is very central and you can go anywhere very easily either walking or metro or shared bikes.
Laura and Olivia are super reactive, always trying to help and very detailed in the explanations they give.
I definitively recommend this place if you want to discover Boston.
I stayed there for 15 nights and for long stay like this, one has to be aware that this is an old buidling which means that you may hear your neighbors (I was lucky, during my whole stay, it was really quiet), the shower and the bathroom are really small (still well-arranged) and that where you sleep, if it is 2 of you, you won't be able to get up without waking up your partner (I was by myself so that was fine)
You can't cook everything given that the kitchen -well-equipped- is almost in your bedroom and you don't want that it smells what you've prepared ;-)
