Whilst we would normally take a hotel for such family city breaks, we took the Penthouse and can now definitely recommend it.
Location is great with local bars, restaurants, bakers etc within a 2-min walk, or 10-15-mins walk to most tourist areas, or next to tram stop and main taxi routes if you want to go further...
Remote Check-in process is professional and easy, everything you need (except milk) is supplied, quality fittings, immaculate finish and condition throughout, loads of space for 4.
Loft Affair Customer Helpline is there should you need anything, we didn't so have no hesitation in saying we will be back to Krakow in the Penthouse Orzeszkowa.
