Peter's apartment in Park Slope was simply perfect for my purposes. It couldn't be better located, right on Seventh Avenue and three blocks away from the F line, which leads to multiple connections through the various boroughs. There are excellent grocery stores within two blocks, and Prospect Park is only three blocks away.
The apartment itself is certainly ample for one person or for a fairly compatible couple -- it's a railroad apartment of cozy construction, but very typical for the area. There is a separate bedroom with a very comfortable bed and a modern bathroom, along with wireless and Apple TV. It was certainly clean and well provided with heat. The kitchen is well supplied and more than adequate for creating simple meals.
In short, it's a little jewel of a place for someone like myself who was trying to do business and wanted more facilities than a hotel can provide.
Anyone unfamiliar with New York apartments might think it's very small, but the fact is that this is what New York apartments look like, and Peter maintains it beautifully. I will be very interested in trying to stay here again on my subsequent trips to New York.
