Alex's place is wonderful for a couple. Has everything you need and its large windows and terraces make for super pleasant and sunny mornings :)
The location is walking distance to Ave Alvaro Obregón where there are many great restaurants and bars. The building, and the neighborhood itself, is very green, European, and safe.
Building does not have an elevator and this particular apartment is on the fourth floor but coming from New York, we're pretty used to it.
I will consider staying here again on my next visit and I highly recommend it.
