I'm sorry to hear about the inconvenience you had with the frozen water. The frost surprised me early this year, so i had not taken the right measurements yet. Now i have, but sorry for the trouble you experienced.
As for the heating i am surprised. The heater is normally great to heat the place with as it is quite strong and the wagon is insulated on all sides. Did you notice you could change the butons to 3 kw and the min-max button to max? It's unfortunate you didn't let me know before, then i could have assisted you or come with another sollution.
As for the directions i'm also surprised by your complaints. I send you a description from aboude station as it is a much easier route (take a left twice and just follow the river and you're there!). You choose to take the metro to gein and when totally lost you called me i tried assisting you, but this was really hard as you could not tell me where you were exactly so i had to guess. When i thought i knew i came looking for you but couldn't find you, so called back and ended up speaking with a woman you came across who reassured me she would bring you guys to the accomodation. I feel like i was very helpful, especially considering it being 11 at night.
True, it's an accomodation out of the city (10-15 minute bikeride) to aboude station and gein metro station, but that is exactly why it has it's different qualities from an accomodation in the city.
