The room smelled musty, moldy, and/or like sewage. There was no air conditioning, just an old fan that was absolutely insufficient in this heat.
The biggest problem remains the location: the hotel is situated on an extremely noisy street, with bars and nightclubs right below. Not a very reassuring street, with many intoxicated people, homeless individuals, and altercations. It is therefore impossible to sleep with the window open due to the noise, but also impossible to keep it closed because the room stinks and it is hot.
In the end, I hardly slept at all. This is by far the worst night I have spent in a hotel.
