We have a lovely stay at Rene's apartment. Rene gave us detailed instructions about how to reach his place and was patient and understanding when we were late.
He informed us of left luggage lockers to use at the nearby station which was very useful as we both had big rucksacks!
His apartment was very cool and spotlessly clean. The kitchen was fully equipped and everything was easy to find.
As long as you are fully aware that you are sleeping in the living room and not in a private bedroom then I would definitely recommend Rene's place. He was very friendly and chatty but also spend a lot of time in his room to give us some privacy. He even let us use his printer to print just a few sheets!
We would definitely stay here again.
