Jiri's appartment was well situated. Taking the bus 207 you will get to the city center in 10 minutes.
Everything was clean, and shampoo and shower gel prodived. Lenka was very nice and happy to help.
From the airport to the city you'll have to take the bus 119, then the tram A until Mustek or Museum. You can get a 3 day-ticket at the airport ( 12€) to use bus tram and metro. Juste have to validate your ticket the fist time and then keep it on your bag for any control.
I went to Charles Bridge, Lennon Wall, the dancing tower (take a drink you'll get the free entry), and more. Take the time to visit Pragua by night.
To eat : I'll defenitely recommend the Mlejnice restaurant for the Goulash and the pork knee which are the best two plates to try in the city.
If you have time, go to CAFEFIN at J. z Poděbrad station ( TRAM A).That was my favorite place. They propose very good breakfast. Go to their INSTAGRAM you won't be disappointed.
And don't forget to try the STRUDEL, which is absolutely delicious!
hope my comment will help :)
