Great apartment and less than 30 mins from the airport. We travelled by bus and underground to the city centre. Very easy and so very cheap. It isn't worth getting a taxi. Views from the apartment were lovely and it was such a lovely space to be in. Lovely and light with high ceilings. Location was great too just a 10 min walk to the centre. Apartment was very clean and facilities were good if you wanted to stay in and eat. Great having two toilets too.
I would definitely recommend this apartment if you are going to Prague.
