We had a great stay. The apartment is small but cosy and with everything you need. Even though the street outside can be noisy, the windows are great and once they're closed you can barely hear anything. The sofa bed is very big, 2 people could sleep on it confortably. To access the bathroom you have to go through the main bedroom, but that was not an issue for us anyway.
The location is very handy, with many shops just around the corner and only a few minutes walk from some of the main tourist attractions. There's also a few bus stops if you don't feel like walking, which will bring you to the city centre in 5-10 minutes.
Edyta and her team were very responsive and constantly made sure we didn't have any issue during our stay. Check in was super easy, and they also left a big folder (and sent a pdf) with tips and recommendations for places to see, where to eat, how to travel and plenty of instructions about the appliances in the apartment.
I would definitely recommend this airbnb!
