Find that *ideal* parking area in the apartment complex where nobody parks. An end spot would be perfect so you can park as close to the curb as possible. This allows enough room on the exposed side of the car in case an ignorant door dinger person parks next to you.
As for washing the car, maybe borrow a friend's hose at their house. The coin-op car washes is an option too. Just use the rinse option to water down the car, fill up your soap bucket, and rinse the car off.
