Just book it!
It's priced well for the area, its private and spacious, check in and out is a breeze, location is prime, the unit is nice and cool and the bed is super comfortable, personal touches are thoughtful and appreciated (extra towels, water, snacks, extra plug in's, movies etc...) and parking is available if you give the block a turn or two.
Seriously, stop thinking about it and just do it!
