Great location and nice and bright apartment. It's a really nice area walking distance from Reforma and Chapultepec park, lots of good restaurants around.
We stayed there in January, so it was a bit cold inside, so Rafael kindly provided us a heater. We still recommend getting some warm socks and cloths just in case:) Also, there's no hair dryer, so you might need to take one with you.
The cleaning person comes once a week if you are staying longer than a week. We didn't notice it in the rules when we booked, because this part was in Spanish, and it was extra charge.
Otherwise we would recommend this apartment to other travelers. It's in a great neighbourhood with lots of action around (nightclubs, bars and restaurant are walking distance away). Yet it's rather quiet in the apartment itself, so you won't be bothered by nightlife under your windows.
