Good advice from Teena- if you can upgrade to Garden View, you shouldn't have to worry about parking lot views, and your request can be "Full balcony please"
I would like to invite you to join us on the BC/YC FAQ thread. Lots of great info and pictures on the first page- we try to keep that updated so you don't have to make your way through all 200 pages of the forum (but you can if you want to!)
