A perfect spot for three friends for a 4 day weekend. In general, I would highly recommend booking one of Francisco and Rodolfo's locations - they were amazing hosts and communication was timely and clear. This location was perfect for us. It's on the second and third floor of a quiet street but with Roma and Condesa a short walk away, and there are a few little cafe's within a block for morning coffee.
The apartment itself is more like a small two bedroom (1 bedroom and a sleeper sofa in the living room) with another one bedroom upstairs off the private rooftop patio. You could easily sleep five people, but there wouldn't be much space, other than the rooftop, for everyone to congregate. There are three chairs in the kitchen.
In the main apartment, the double bed is super comfy and the ceiling fan was a bonus. The single sleeper sofa in the other room was fine for one person for 3 nights. The bathroom was everything we needed - very clean and the hairdryer was great! We didn't use the other bunk bedroom, but the beds (and attached bath) looked really nice. One thing we noted is that it was rather warm in the bunk bed room, so it might not be ideal in the hotter months, but we could imagine it would be perfect for a couple kids/teenagers.
Overall, I would definitely stay here again!
