We had a great stay at Yasu & Akiko's place. The pictures don't do it justice, everything was spotless and communication was prompt. Our room had really good A/C and good wifi connection. The amenities were just what we needed for our 4-day trip, with a lot of space for the two of us and a private bathroom. Our room was on the third floor with two sets of stairs which might prove issue for some, but was fine for us. It was a bit hard to confirm if our door was locked from the inside as it automatically unlocks when you open it, but they have an additional chain lock that we used as well.
Location was great, walking distance to the subway station and still quiet despite its proximity to times square. We had a late flight returning home, but we were able to keep our luggage on the second floor with locks provided. We enjoyed watching their tiny pet turtles in the kitchen.
