Pros:
Beautiful neighborhood with lots of nearby transit options, nice tenants, high quality appliances, regularly cleaned hallways, and the unit was virtually soundproof compared to other pre-war buildings! It was a great first apartment and I look back fondly on it.
Cons:
During the few years I lived there, the owner had sold the building and we were under new management. The new management did not respond to problems as quickly - including the messy trash area outside and the bugs that came in from the poorly installed windows. I remember bugs were the worst when the summer heat rose, and my curtains would blow from the wind - and yes, they were fully shut. The flooring had gaping holes around the radiators, too - but that never caused issues in my case. Outside noise wasn't too bad, but it is near a fire station - so that's good to know beforehand. The building door also locked automatically - which was unfortunate if you forgot your keys, and my buzzer also did not work (had to go up and down a lot of stairs to get any deliveries or let in guests.)
Advice to owner:
If management has not changed in the last handful of years, I'd say to just stay more on top of things and fix interior issues like windows or floors.
