It was awesome! We came and met Pavels mom and she gave us the keys, the accommodation was really good, clean, enough towels, close to the center and some shops, i advice to go shopping at Alberts its a mall in the main street, i also advice to stop with metro at Mustek if you come to prague, thats closer.
Prague is an amazing city you must go to the John Lennon wall and do a segway tour, near the river or hire some bikes. (there can be some hills ;p)
If you wanna party go to club Roxy if you like clubs that are not too big, otherwise i prefer club Karlovy lázně, it has 5 floors with different music, i really liked the oldies music.
And if you take a taxi always make sure you tell them the price you want to pay for before you go in the taxi. We payed 300 czk for 4 persons.
