Perfect location - just steps from the main square and all attractions in the historic center. Delicious street tacos are just a couple of blocks away, available even late at night.There's a concierge 24/7, so the check-in/check-out is easy, and they are helpful with everyday questions. The host was very responsive - there were mosquitos in the apartment when we checked in late at night, we contacted the host, the host immediately arranged a mosquito spray and a mosquito repellent plug, and we had it in 30 minutes. The bedroom and the living room + kitchen area were well sized and enjoyable. The bathroom was nice, and had a spacious shower, great for tall people.
Things to note: The apartment doesn't have A/C, like most places in Mexico City. We had to open the windows in the morning and at night, but since windows don't have a mesh screen, this did let in a few mosquitos (this isn't specific to this apartment though). The apartment was on the first floor, and there was a garbage truck parked under it almost every morning, so we couldn't open that window :-) Only 1 set of towels was provided for 2 weeks, you may need to either wash them or bring extra. There are only 2 wine glasses, 2 cups, 2 plates and 2 soup bowls.
We loved the apartment, we'd stay here again.
