Isaac's place is a great option for a family or 2 couples. La Condesa is a very safe residential neighborhood with lots of coffee shops and restaurants within walking distance. Lots of tree-lined streets and perfect location for a walk around the neighborhood.
Apartment was as described, very spacious and comfortable.
Check-in was a breeze and Isaac was a very responsive host.
I highly recommend his place. It is a great option if you want to explore and enjoy Mexico City.
