Even if we only stayed one night in Sigrid's apartment, we enjoyed our stay there. It is very well located, clean, quiet and well equipped.
Communication with Sigrid was perfect and she was also flexible on our arrival (we were in a hurry as our boat was late and we had programed a hike on the stromboli just after our arrival). Sigrid is a very nice person who has the sense of welcome, we strongly recommend her apartment :)
