Pros:
Landlord is attentive and timely, at a top floor and never even had to turn the heat on in winter (but it's not overheated either), laundry is $1.50 per load with two of each washers and dryers in the next building, neighbors are both nice and keep to themselves, barely any outdoor noise, haven't ever had electricity/internet outages or leaks, one in-window bracket for AC, bike storage in the basement of the adjacent building, garden in the back is beautiful (and the front of the building and street in general are, too), no mice or bedbugs, gas stoves make heating up things really quick
Cons:
Price for the amount of space, wish the monthly exterminator service was more effective (but only encountered 4 american roaches in nine months), walls aren't thick (but it's not more disruptive than most older apartments), need to be home to accept deliveries or packages can get stolen (but this isn't uncommon in NYC), difficult to get bike down through skinny basement stairwell, big holes above window moldings, bike room isn't the cleanest (but it's a brownstone basement so not unexpected), older kitchen appliances
Advice to owner:
Ask the exterminator to gel the basements. Otherwise thank you for being great!
