I do take deposit, which i indicate in flat listing. I am sorry you didnt read it. Water heater takes 15min to heat up (thats how is was at least) if it too more time i am sorry for it, i will check it myself. About internet as i mentined on the page is 10euro a week, unfortunately you havent informed that you will need it, so i want able to fix it at the check-in. There is external heater in the flat, which is there since forever, i am sorry you didnt noticed it (i can send pictures of it in the flat in required), in addition you could use air conditioner for heat.
Well, if you had questions you would just contact me and i would answer to all the questions, but i havent got any requests from you during your stay except comment that you left me after your stay
