In the absence of dedicated space / drying / washing facilities most of your gear, including kites, can be rinsed of in an average shower. Boards can be left to run of in the shower. Same for a kite - just takes a lot longer plus - you'd have to work it through the length quite a few times.
For everything else - there's a balcony. This contraption has been working for me for years:
