what level are u on? is the drumming above or below you?
I'm on a lower level, facing the pool & can't say I have heard any drum beat.
Maybe its the music from number 205 - Apartment 205 has a couple of party boys living there, and they play their music LOUD, especially on a Friday after work into the night & Saturday nights.
#205 also have big parties with lots of people coming and going at all hours. I'm not too close to them, but for the apartments around #205 it must be hell on weekends.
Are you near #205 Evelyn?
