We stayed at Simon's for 2 nights and found the location to be very convenient. It is far enough out of the CBD and yet not so far out to be inconvenient. If we wanted to, we could easily have walked (albeit up and down a significant hill) to the Wrest Point Casino area. If you don't mind a bit of a gamble, Simon even has a poker table and poker set in the apartment for use.
The bed is very soft, it was like sleeping in a cloud. The underfloor heating in the kitchen and bathroom was a great bonus on chilly Hobart mornings.
Check-in was easy and communication was prompt and helpful. The only thing to note is that you will need to provide your own milk and other pantry supplies if you want milk in your tea and or coffee and want to cook. The coffee pod machine with ample pods was very much appreciated.
Overall, a very good experience.
