If you are looking for a bed and a roof, this place is great! The location was very nice, but the apartment itself was very noisy and not at all private. The "main bedroom" was just a bed in the living room - there was no privacy to sleep at night or even change your clothes. The second bedroom was better, private and had a door with a lock. Although the housekeeper was very nice and polite (she spoke no English), we had to ask for a second set of towels as we were only given one (even though our reservation indicated 2 visitors) and we had to ask twice for more toilet paper as only one roll was given. The key to the sliding glass door/wall was very finicky.
The location was really the best part - easily walk to anywhere in Polanco and the street felt very safe. Keep your expectations low for the rest though. We did not have great communication from the host leading up to our trip but the co-host contacted us via Whatsapp to confirm details once we arrived in Mexico City.
