One of the worst places I have every stayed in Mexico City. It was so bad that I immediately had to go find a new place to stay. For starters, this place is like a hostel--mulitple rooms and different guests staying in each. My room was CRAP!! The bathroom was FILTHY!!! ABSOLUTELY DISGUSTING! The floors creaked and made a loud noise every time you walked on them. The room had no window and no source of air. There was a fan placed in the room but it was OBVIOUSLY broken and no one had bothered to fix it. So, imagine a hot room with no window and a broken fan. Such a sad excuse for a room. Not to mention the bedsheets hadn't been cleaned properly, as there was human hair in the sheets. Check-in was not a smooth process either--especially frustrating when it's 5 AM in Mexico City! The code in the listing for the lockbox was different than the code I was supposed to use, so I had to call a few people to get help--at 5 AM. Finally, one person answered and it was hard to hear what they were saying. Not necessarily his fault, but the instructions could have been clearer as to which box to use and which key to collect.
