Walter was friendly and replied quickly always. The accommodation was near the city center and only 15 minutes away from the train station. Unfortunately the flat was really dirty and in the bathroom was mold. So we didn't feel comfortable. The wifi signal was so weak that we couldn't connect to it and the air conditioning worked, but it but didn't cool. Moreover some of the statements Walter claimed on the website weren't true (good equipped kitchen, view on the sea/ skyline, equipped bathroom, good working space with door).
However Walter was friendly and flexible with the check out.
