Mark's place is very conveniently located, close to Chinatown/Gastown, minutes drive to downtown core. It's far away enough from E. Hastings, so you don't have to worry about that. Security is great in the building, key fobs are needed for garages, all entrances and elevators.
The unit itself is very spacious, clean and bright. The unit gets a lot of sun light, so it warms up (bordering hot - even in September) during the day. Wi-fi can be a bit spotty, Netflix would stop every now and then to 'buffer'. Washroom was clean and water pressure was good (if you care about that sort of thing).
Communication with Mark was great, and everything was done via messaging, but there weren't any problems with check-in or check-out process.
