My boyfriend and I stayed in one of the Royal Belazza apartments for 4 nights in December. The place is fantastic and I would highly recommend it! Not your typical Airbnb rental, the Royal Belazza apartments are actually a large number of apartments all in the same building. It's a very professional operation with a doorman, light daily cleaning and airport transfers organised on request. The rooms are beautiful, clean, spacious and well-maintained. We booked a studio apartment but were upgraded to a one bedroom apartment for free which was fantastic! Ivan was great and very helpful. No complaints from us at all. We'll definitely stay there again next time we're in Prague!
