We spent 4 nights in Alan and Kasia's apartment and we left with mixed feelings about the place.
The apartment is well located, in a nice area with options for breakfast, groceries and everything you need for a pleasant stay. Also, they were really nice and allowed us to check in 90 minutes earlier.
On the downside, we didn't receive at check-in the baby crib which was charged 40 euros extra. I had to call all the numbers I had from them and nobody picked up, ultimately I messaged on Airbnb and got an answer and the bed and mattress were brought to us later, by the cleaning lady. I was also disappointed by the quality of the bed and the mattress, as they're the type that retails for about 60 euros, yet I was charged 40 just to rent them for 4 days.
More effort could be put into cleaning the place. as it was really dusty. All the doors were really really squeaky, so our kid would wake up each time one of us would move through the apartment or open the front door. I solved that on my own, with some WD40 I bought. The fridge is really small and the kitchen water tap sprays you when using it.
Also, the place is quite cold. We visited in July and there were 19-20 degrees in the apartment. Being on the ground floor the floors were cold and the high ceiling didn't help either. Slippers would be a nice addition to this place! I had to go shopping for some after a couple of hours in this apartment.
All in all, the place has potential, it has its positives and negatives but could definitely use better management overall. I gave 4 stars for the apartment, I would give 2 stars for the StayBearlin services. Cleaning, better communication, small amenities, and some maintenance, could improve the overall stat by a lot!
