Excellent 3 night stay. The building was easy to find and even though the unit was on the first floor it is in the back and very quiet, night and day. The location is excellent; a couple blocks from Reforma, in a very safe neighborhood.
Highly recommend La Naval right next door both for wine/spirits as a package store or as a sit down restaurant for tapas.
Although we didn't use them we appreciated the fans in the bedrooms in the event of the weather being warm.
We used the washer/dryer (all one unit) and had a bit of a hard time understanding the settings for the dryer so instructions (in English) would have been helpful but we figured it out.
The kitchen is well equipped although we did not do any major cooking. It would have been nice to have coffee (not instant) and a small container of milk to get us through the first morning until we had a chance to stop. Other suggestion is to replace the towels -- they are awful!
Nice place and we would stay again.
