Ehhh
We stayed at the Parc55 in early March 2012. It was ok, but needs a massive update and I probably wouldn't stay here again.
We got a corner room on the 21st floor. It was so loud from both outside noises and the rooms down the hall that it was next to impossible to sleep. The walls are so thin that housekeeping was knocking on the door across from us and I opened our door thinking they were at our room. The direct quote from the housekeeping staff- "Sorry, these walls are really thin."
As if the noise were not enough, the bed was one of the single most uncomfortable beds I have ever attempted to sleep on. It was terrible.
The hotel lobby and restaurant are very nice and the room was very clean. The location was pretty great, as it is right by the end of the trolley car line. But it is not worth the price.
