We stayed at Mark's apartment for 6 nights. Room is as per photos provided and is very spacious. The room is on the penthouse level and was very quiet. We stayed during edc week and the noise from the wet republic downstairs was minimal. The location is about 10 mins to MGM grand hotel and is all via an inside walkway. We did not need to contact Mark during our stay as there were no issues. However, prior to our arrival Mark always replied quickly. The check-in and check-out process is a bit slow-i would recommend to do mobile check-in and check-out to quicken the process.
