I've been in Krakow for 4 days / 3 nights, was staying in this nice apartment hotel and booked two apartment rooms. After booking I recieved a confirmation mail. I also got the information that the building is fresh built so there could be a little bit dust. Actually the hotel and our two rooms were super clean, everything's new.
The concierges were all very friendly. The check-in and check-out were uncomplicated. Our rooms were ready before the official time for check-in and we checked out at 4 am.
The rooms are equipped with a queen size bed, a nice bathroom with a shower (towels and shower gel included), a flatscreen tv and a small kitchen with dishes and kitchen utensils. So if you want to cook your own food you can go for it.
The most important thing: the location of the hotel is perfect. You can easily take a bus from and to the airport. You can walk to the old town of Kraków or the Wawel castle within a few minutes as well. Cafés, restaurants and small markets are nearby.
If I'll travel to Kraków again, I'll definitly choose this again.
