The apartment was overall OK, very well situated in the Back Bay.
However there are a couple of things, which are annoying, especially taking into account on how expensive the apartment is.
1. The fridge is extremely noisy and makes it hard to sleep in the night
2. There is no towel/bed sheet replacement during the stay, a little hard if you are staying for longer (I stayed 2 weeks) and no cleaning service during that time. It would be reasonable to get new towels at least every week
3. The window blinds are very low quality, so the apartment is really bright at 5am in the summer
