I'll rate our stay at Sei's place a three out of fice stars. The location was just a few minutes walk from the station, you can easily find it since the directions given by Sei can easily be understood. The space is quite small but since it is located in a big city, I guess it's just normal. But I was really disappointed with the wifi, it doesn't work most of the time which makes it hard for us to communicate with the host. Second, the hot water is not working. In our 3 day stay there, the hot water only worked once. I told Sei that I guess it is already out of gas, but nothing happened. If only the wifi worked well, I guess we could have communicated better.
