When I had arrived I knocked on the wrong door. Hovewer the neighbor was very nice and he showed me the helen's house. It was the next one :)
This mistake is usefull to me to say that the house is placed in a peaceful neighborhood.
Helen is a great host also if she felt a little bit sick that day. When I arrived a welcome-cup of tea and a bottle of wine waiting for me. The bed was confortable and there were fresh and clean towels every day. In my room I found a phon too, not specified in the ad. During my stay I felt at home, my only regret it was not saying goodbye to Helen and her lovely cats because I went out at 5am.
