Namio answered always very quick and informative. The flat is very easy to find because Namio add a map and photos in the map that it is unpossibly, not to find her place. I went to Nezu Station but I had to buy 3 different tickets and could only pay cash. Sometimes it was not easy to find the right track. So I recommed to get off at Kensai Ueno Station and take a nice walk to the flat. The flat is located in a quiet and save neighborhood very close to Nezu Station. From Nezu Station it is very easy to go anywhere in Tokyo. I never saw Namio but it was not necessary because she always answered quick and informative. When I checked in, a man took my bags to the flat and told me to send a message, when the flat is cleaned for check in. That worked very well. When I checked out, I just droped the key in the mailbox downstairs. No easiear way to ckeck out.
