We had a great stay at Silvan's apartment. Communicating was easy and fast. Silvan offers groceries to order in advance that are waiting in the apartment when you arrive, which is very convenient. The apartment was very clean and kitchen, shower and washer worked well. The wifi worked great, but stopped working during a thunderstorm. When I texted Silvan about it he showed up after a few minutes and fix the problem. It was always possible to find a parking space within 100 meters of the apartment and most of the times right next to the apartment.
I would have rated the apartment 4 stars, but since Silvan was such a attentive host, I have rated our stay with 5 stars overall. The apartment could be improved by having more comfortable mattresses (the simple spring mattresses don't give a lot of comfort), by fixing the missing cupboards in the kitchen en move the cupboard above the kitchen sink to the left wall and replace it with just a mirror so that the bathroom sink is more accessible.
