I've been staying at Hotel PF the last few years I've come into Mexico City, but recent issues will give me pause in the future. The staff are excellent--check-in staff are great, and the housekeeping staff are absolutely fantastic.
However, the facilities are becoming a bit dated; there are unpleasant odors coming out of the AC system, and I feel the temperature control is not great. In February, it can get a bit cold at night, even with the heat on. The shower temperature was another issue, with the water going hot and cold unpredictably, making for uncomfortable showers. Lastly, I've also had some issues with the shower not draining properly. I want to continue to like this place, but I would like to see them update their equipment and plumbling systems.
