Andreas place is indeed a 4 room apartment.
Not mentioned in the description: there is no suitable space available to sit and hang out after a full day of exploring the surrounding areas. It is obvious that this apartment was originally designed as a 2 or 3 bedroom apartment with kitchen and a living room and or dining room. Sitting on a picnic table like bench at the end of the day was not the most comfortable way to talk about our adventures from that day. Andreas would be well served to eliminate bedroom #4 and bring back the living room furniture.
Messaging between us was effective. I should have asked the "living room space" questions. Lesson learned!
