I was on the impression that the Entire place was for myself but the private room I had was lovely, it's a Library/Room there are tons of interesting books, the place is cozy, clean, and Edith was very nice and service full.
I recommend stying in this places since it's awesome and near to many point if interest, Mercado de Coyoacán for example is a must, the local Tianguis (street market) and you are about 15 away from El Zócalo with light traffic, 35-40 with peak-hours heavy traffic.
