It was an individual room in a family house and Marga (the host) was extremely nice, helpful and kind.Very close to the Embajadores metro station.
I could only stay one night and I got to the house when it was already dark so don't really know how close to some attractions is but Marga showed them in the map and looked fairly close.Take into account that there are at least two other (non-individual) rooms for rent so chances are you won't be the only guest in the house during your stay.
I would recommend this accommodation since the host and the room were nice but as I said, I basically only slept there and left in the morning.
