When we (3 female traveling students) arrived at the address (we reached it very easily), Jarin was already there waiting for us. He welcomed us very friendly and we felt comfortable instantly. He showed us the apartment, how everything works, and gave us good insider tips what to do and where to go. He also made us aware that other guest would come (there are 4 rooms for at least 2 persons) that might be a bit loud. The room in the is huge and even though it is a souterrain floor, it was pretty bright. Thanks to the double window noises from outside didn't come in. There is one shared bathroom and one shared WC and a very small kitchen. Hair dryer, towels and a fridge with few drinks were inside our room. In the hall outside there are many maps and tourist information exposed, we could look at.
The apartment is close to the Dancing Building and so to a tram station. But you take just 10 to 15 minutes walking time to the Charles Bridge and other 5 minutes to the Main Square. Despite the small minimarkets there is a big Billa supermarket in walking distance, but also bars, restaurants, and everything what a traveller needs. We felt very good and we definitely will book this room, again!
