Wolfram was very attentive. Questions were answered very promptly and comprehensively. It turned out he was near the airport when I arrived so I even got picked up from there and taken to the apartment - wow! The apartment is very nice and has everything you might need for your stay, including a few things to welcome you - a bottle of wine, some juice in the fridge, etc. It was a little darker than I had anticipated, with all windows facing the inner courtyard - but then again, this meant it was a very quiet and tranquil location despite being right in the city centre. Wolfram was also very flexible about the check-out time. I have no hesitation in recommending this apartment or this host.
