Dear Jay, thanks for your comment.
As you may know I was away as I told you in Japan and it was complicated with the difference of time between the two countries to answer everytime.
It's not right to say that I didn't answer to you when I pratically answered to all your messages that you have sent to me and you have sent a lot each day for the wifi, for the light, etc... So for one message not answered, it's not very cool to say that.
For the bathroom, there is no curtain but I'm sorry I wash everyday in it and there is no water all over the flat as you say, you just have to be careful. As for the water from the ceiling, unfortunately it's a problem that I could'nt now will arrive, I took now all the dispositions to solve the problem. As for the cleaning I have a professional doing it, so I don't see any problem in it.
Hope you enjoyed after all your stay.
