Awesome place! We rented the 4th and 5th floors for 5 people and that space worked great! 1 full bathroom in each apartment (2 total), can walk to akihabara or the train is about 7 minutes walk. Communication was always excellent and the place was very clean. There are a few flights of stairs to climb but we didn't have a problem with that (travellers in our 20s) also the place was very quiet at night and through the day. Air conditioning worked awesome and lots of hot water! Highly recommended!
