I cannot recommend Sandy's place highly enough.
Its location is ideal - 2mins walk from Central Park, 2mins walk to the subway (local and express trains mean most areas of the city are a short ride away). The street is peaceful and safe.
The room is a good size and the bed super comfortable. The living/kitchen area is spacious and has everything one could require.
I only met Sandy twice - once at the beginning and once at the end of my stay - but she was the most welcoming, friendly and interesting host. When she was away she kept in touch, checking everything was ok and offering any advice I needed.
I'll be back! Thank you Sandy!
