One of the best rental deals in Murray Hill is a little pre-war building on 36th and Third. I had a client who lived there and she said it used to be a mansion, but has since been converted. The more units I see in this building, the more I believe her. Almost every single unit has a a fireplace, there are tons of windows, built in bookcases and random balconies.
This mosaic is in a one bedroom that is available for $2400. I was amazed it was still intact, but more curious about what the space was used for before the building was converted. It's on the second floor, so it very well may have been a dining room or some sort of parlor.

Midtown gets a bad rep for being devoid of charm, but there is a great building on 48th and Third that has a leafy, common courtyard. Most of the units are large one bedrooms, otherwise I was totally live here. It's like something out of 1920.
