The Olimpia Hotel is located very close to the Piazzale Roma, where one gets taxi's and buses etc. Therefore, one does not need to drag his/her suitcase all over the busy, crowded Venice "streets"! And, we had one of those 6am flights so leaving needed to be as convenient as possible. Lara, at the front desk, was very helpful in securing a driver for us- especially one who would be available to come at 4am.
The hotel is a little funky in accessing our room- we used the elevator to take us up one floor, then down a hallway and up some stairs, and down another hallway. Other than this, the room was comfortable, and quiet and the AC worked almost too well! The bathroom was tiny, but shower pressure amd hot water both very good.
