Like in many Brownstones, me and my roommates rent the top two floors while the landlord and his family live downstairs. While there are multiple entrances, there is no locked barrier between their home and our hallways, landings and kitchen. Upon requesting that they respect our privacy and peace by notifying us before entry and by refraining from noise (loud arguments in those hallways), we were informed that they have total access to all but our bedrooms, as if it were a boarding house. The lease does not specify where our “unit” begins and their personal property or shared space begins. Any advice?
