Me and 2 friends stayed at Marek's place for 3 nights. It was great, the apartment is amazing, super clean and wonderfully decorated! The private terrace is huge and perfect for a nice breakfast in the sun. Marek showed us around after check in and gave us great tips. He is a very friendly host who only wants the best for his guests. I would recommend anyone to stay at his place and will do the same next time I'm in Prague :)
