Katerina's apartment is really great. Big enough for very comfortable stay for two people. Well communicated, close to the subway station, in great neighbourhood full of friendly people.
We didn't meet Katerina in person, but she was very helpful whenever we needed anything and she sent us clear and comprehensive instructions how to get there, how to use appliances, etc.
If we're ever coming back to NYC, Katerina's apartment will be an obvious choice for a place to stay :-)
