Uncomplicated communication, very responsive. The apartment is beautiful, conveniently situated, was clean and had everything we needed. We really enjoyed the stay.
Noteworthy features: washing machine, mobile heatings (for "winter" time travellers), window covers that can black-out the rooms
(Things that didn't bother us (!), but might bother others: kitchen is equipped with a stove plate and microwave (+grill function) but no oven, during "business hours" the you will notice the cars going by and any noises from stairwell, some streets in this area might be overwhelming to some - it's whatever you are used to from your hometown I guess)
