We arrived very late at the hostel. However, Ivica's mother welcomed us very kindly. she spent all the necessary time to explain the rules and answer our questions. She also explained us the reasons for the 30€ per person deposit (that we get back without any problem).
Ivica or his mother are present anytime to manage the hostel and you can ask them anything.
Prague is a lovely city with tons thing to see and do. There are tons of transport means (We took a 3 day pass which was perfect) that are easily accessible (trawmways, bus, metro). We were 10 people and we specially recommend 2 activities: the electric scooter tour which was very instructive and the bobsleigh runs. There are a lot of others things to do, I'm sure you will find yours (culture, beers, sport, beers, relaxation, beers, ...).
It was a great journey for us.
