Nas & Erika were great hosts. Although we didn't meet, they provided clear instructions on the self-check in process and a guide on how to use all the different facilities. The apartment was clean, comfortable and in a quiet part of Shinjuku. Towels, toilet paper, soap, shampoo and washing powder were all provided. We even got 2 large bottles of drinking water. It's about 10 mins walk and pretty easy once you work out the direction to the main station. Underneath is an Italian restaurant and within a few minutes walk there is a family mart (convenience store). On the way to the station, there are plenty of bars, cafe's, shops and restaurants. Great place and location and would definitely stay here again when we're back in Tokyo.
