This apartment (no. 5) ticked all our boxes. Located in the Kazimierz, the apartment offers a good choice of restaurants outside the front door, and is a short walk to a tram stop, taxis and mini-market.
It is comfortably and smartly furnished with full kitchen, with dish washer, sofa, dining table and chairs, in one room and a separate bedroom with generous cupboard space and a small desk. My only reservation was that the bedroom is small and not much space between bed and walls. OK for us but may be a problem for larger people. The bathroom, with walk-in shower was functional and modern. Plenty of shelf space. It has a washing machine.
There is no elevator. Staircase is wide and staff helped with luggage.
Wifi was secure and strong. Air conditioning worked well for which we were most grateful as temperatures were high.
Reception is normally from 9am to 9pm but staff wait for late or delayed checkins. The reception and cleaning staff were welcoming and helpful in making phone calls and booking taxis.
The units are serviced weekly, daily service costs extra but towels were changed every second day at no charge.
Breakfast can be taken at extra charge at the nearby Rubenstein hotel. We didn't do this preferring to breakfast in our room with supplies from the minimart.
For us, Crystal suites was ideal and I highly recommend.
