Disappointment.
Yes, the location is great and the apartment is big but that’s all.
Beds are awful, and some are really broken.
Bathroom and toilet are tiny and smelly.
The apartments is very very poorly equipped. I have been in more than 10 ABNB apartments and this is by far the most basic, "naked" and not inviting.
And one more thing - the location (right above Hitler's bunker) should be disclosed in advance. Little children may be afraid from it and this is an important factor that should be known before making the reservation.
