We stayed at Ondrej’s place for 4 nights in Prague. The check in process was very easy, we didn’t arrive until after 10pm and the hostel in the same building was able to allow us into the apartment which was very convenient! Ondrej also very kindly booked us airport transfer which made the whole process very easy. The location of the apartment is superb and you don’t need any public transport, everything is practically on your doorstep.
It was very hot in Prague during our stay, although there was a fan available it still was quite hot at night trying to sleep. Very nice place.
