Starting from the beginning:
Kasia is great with communication, she is quick, her english is great.
Our flight was delayed by two hours and she stayed to let us in with no problem and in fact she was very kind in her communications.
We got there via Uber and paid around 12euros. The neighborhood is lovely, there are many good places to eat and cute coffee shops to hangout and work only 5-10 min walking distance. The apartment itself is wonderful, bright, recently renovated and very clean, the air conditioning was a huge plus since the flat is located on the top floor of the building so all the head would get trapped in there if it wasn't for the windows and the AC. We didn't need the ac during the night, the skylight would let the breeze in which was pleasant. The shower drain is very slow and seemed clogged to me but apparently that's how it works, I am sure Kasia will have someone else to look at it again.
The shower pressure was great and overall lovely.
Just be aware there are many stairs to this unit. I did read it in the description and took it lightly. We had two 23kg luggage, two carryons, one backpack and one purse. It was a lot of work taking them up the narrow stairs and down. My husband and I did a big workout and not complaining, but would pay more attention next time.
when checking out, we asked Kasia if we can stay abit longer since our flight wasn't until later in the day and she graciously obliged as she didn't have the next the booking.
All in all, Kasia's place is lovely and a place you look forward to go to. I would definitely stay here again with less luggage. hehe...
