The main problem was there was no air conditioning. We were fortunate and it rained that night and was a little cooler. However, because the windows were open, there was A LOT of street noise until about 4am in the morning. We only got about 2 hours of sleep!
There was also no elevator. We only had an overnight bag so it was not too bad, however, the stairwell was very hot and the lights (automatic) kept going out which made it hot and pitch black!
