The host communicated very well. The check in was easy. There is always security that let you into the building 24/7. The apartment is walking distance (about 3 blocks) from the metro Balderas. The apartment is nice and has the basics. The hot water is a little bit tricky, we found out that it worked in intervals of 1 minute, then you have to turn it off and wait for a little bit, then you can have hot water other minute, and so on.
