We arrived late as we went to the wrong train station, but Kazumi was very nice to text me to ask if we are lost as we were supposed to meet him at the unit. We were delayed for so long and Kazumi was very nice to leave the key inside a secured box and we could retrieve the key there on ourselves. Throughout the trip we did not meet him personally but he was very helpful to answering all our queries even if it was late at night. The apartment was very cosy and located at a very quiet street. However, 24hrs restaurants and convenience shops are all within 5to 10 mins walk. The nearest train station Nishi-shinjuku gochome is also about 5 to 10 mins walk. Everything in the apartment functioned well and we were glad we made the decision to stay there! Having a washing machine was very convenient and we could just hang our wet clothes outside and it would be dry the nx day. Don't even need to go to the laundry shop for drying. We were there for 6 nights and definitely recommend it! Will definitely book again with Kazumi when I return to Japan again. :)
