[Mister E]

Hi everyone, a long time ago (~10+ years) I saw part of a movie about a young woman who moved into a creepy apartment building that had an extremely deep swimming pool in the courtyard. As I recall, the residents were all somewhat strange, there were secret rooms and passages, and the whole atmosphere was somewhat dark. The only real plot point that I remember was the pool, which was unusably dirty, supposedly very deep, and may have been drained at some point during the film. Unfortunately, I don't remember much more of the plot, actors, or title. It was most probably made in the 1990's, although it is possible its from the 80s. Anyway, this has been bugging me for years, as I would like to see this again out of curiosity if nothing else. It may not have been a horror movie in the strictest sense but it was strange and I didn't know where else to ask. Thanks for any leads!
