The apartment was just like in the pictures, very clean, comfortable, and centrally located.
Ilse and Diego were very helpful hosts. They got an extra bike for my boyfriend to ride and provided a back-up network from elsewhere in the building when the wifi went down. They even put up a dark shade for me in the bedroom window because I told them I was sensitive to light.
I stayed there with my boyfriend and a friend but it has room to sleep four people comfortably.
I will probably try to stay there again if/when I return to DF!
