We had a great time staying at Alberto's place. The location of the apartment could not be better. Very quiet and yet closed to some of the best restaurants and bars.
We were 5 people. We went out every day to enjoy Mexico City's beauty and gastronomy, so we didn't cooked or used the kitchen. There's a grocery store two blocks from the apartment just in case you need anything. To the left of the apartment building, there's a cute and cool organic store were you can buy seeds, nuts, soaps, herbs, etc. and to the right, there's a small restaurant where you can get breakfast and lunch!
If you have a party of more than 4 guests, the pull-out bed is a good option, but I was told that the tv couch was not as comfortable (we were there a week). Overall, we LOVED the apartment and we will certainly be looking to stay in this place again the next time we visit Mexico City!
