My friend and I stayed here with our infants and we had a great time. We each had a bedroom and a bathroom. We asked for baby chairs and cradles - and no fees were charged. Even though we were delayed 2 hours, we were still welcomed with a smile and a good introduction to the apartment. Unfortunately, there was no sun at the terrace during the evening. I think the sun comes after 11 am.
There is an elevator in the building but it is really small. But luckily our strollers could fit in it.
The area was nice with small shops and cafes. The metro Pueblo Seco was really close, but we walked with our strollers around the city instead of taking the metro.
I would recommend this place to stay and also if you are traveling with small children.
