Stayed a few days in this hotel. The room we had, 511, next to the emergency exit, was large, clean and comfortable. However, the first night the adjoining room was occupied and we heard the people talking. They were talking at a normal level, but we couldn't catch our sleep because of it until our neighbors went to sleep too (luckily they didn't stay up all night). After that the other room was empty for the rest of our stay, so no more sleep deprivation.
We also had a power outage for 30 minutes during our stay, but that was not a problem for us.
