Sun was very helpful and friendly with us at all times; communication with him was always prompt and courteous. Sun's apartment is very spacious and comfortable, in a quiet part of the neighborhood. We had everything we needed at our fingertips! Two metro stations (three different lines) were within steps of the apartment, and so were grocery stores and restaurants. Our visit to NYC was wonderful, and staying at Sun's apartment made everything easier. We hope to stay there again in the future!
