I had very good experience with Alicia's place, located in the upper Manhattan, a subway station is less than 5 mins away from the apartment, subway line #1 goes to anywhere in the city, good location even better people. Alicia and her family are very warm and kind, willing to help you along your trip plan. The room is comfortable and private and there is an extra door to exit/enter in front of the room so its very convenient in case you have to leave or come in the late night.
Highly recommend this place if you want to meet great people.
Thanks Alicia.
