First and foremost, I would avoid using the parking instructions from the leaflet because it is fairly confusing. Directions state to use the fob on the “yellow lifting barrier”, however the barrier is actually red. There is an actual yellow gate that is in the structure, which should be avoided, unless you are looking for an awkward/panicking situation of backing out with a line of cars forming behind you. Instead, watch the youtube video that he sends you, via email, and if possible, download that video as well because there is no service in the structure. However DO NOT follow the video step by step as instructed because at 1:30 he does run the stop sign. The pain of parking is worth it because it is free.
The place was clean, the host was communicative, and the location is great, with a couple of street cars nearby.
