Through all these years travelling exclusively with Airbnb (both alone and with children) we've had a bad experience only once. This stay is most likely second worst stay we've had so far. Here are the key points.
1.I don't recommend this place if you are staying with children/babies. It has zero amenities and we've been asked to pay extra 10 euros for a baby cot. In all of the Airbnb places we've stayed so far never ever we've been asked or charged for baby/kids items.
2. Location ist not particularly nice, the area is run down, there is dog shit and garbage all over when you step out, it is stinky and not stroller friendly.
3. The flat itself has a bad ventilation, after you take shower it starts to get smelly and dump. In a soap holder in one of the bathrooms we had a liquid mixture of soap mixed with water instead of a regular soap. The shower is super tiny and the shower curtain was destroyed so we ended up with water all over the place.
3. Communication. Probably the worst part of the whole stay. The host offered us a taxi pick up and we've agreed to pay extra 10 euros for 2 children seats. When the taxi driver has picked us up upon the arrival he told us there is no space for one adult. We had to take away 1 seat in order to fit in the car and sacrifice security rules. But we still had to pay the full price for this ride.
During our stay the building was sprayed against pests, including our stroller that we left behind the door. The neighbor came and told us we have to wash it because it is highly poisonous for small kids. When I wrote to the host, she said she has no idea and anyway we should not leave anything behind the doors. She also hasn't answered my WhatsApp messages even though she gave her number and said she would be accessible. This attitude is surprising, something we've never experienced on Airbnb before.
All in all our experience was weird considering all the good reviews this place has. We left the flat one day earlier and checked in a hotel (that offered us free baby cot and had nice functioning shower 😊).
