The communication worked great! It was always answered very quickly. The check-in is open 24 hours so you can check in flexibly. There are three great, large bedrooms with double beds where in one bedroom are two single beds (you could also in principle sleep two in each). Nice three modern bathrooms all with toilet and shower. Air conditioning can be easily booked (tell at check-in) but is actually not necessary because the apartment is on the first floor and it is pleasant! I would definitely recommend the stay :)
