STAY HERE!!
Nothing but good things to say about Hostel ELF. The place is really really cool, they clean multiple times every day. To me the most important thing was the bathroom, one thing I don't like much about hostels is that there are common showers, it gets crowded and it's not very comfortable BUT at ELF the showers are individual with a private door, sink and mirror... hot water on point and they provide clean towels. Since I'm in the middle of an euro trip I even did my laundry here at a fair price. Breakfast is also included!! And a very good one, 2 types of bread, 2 types of cheese, ham and salami, coffee and múltiples teas options. Bed, pillow and blankets were good too. Bus stop is right outside and in 15 minutes you're in downtown Prague, for the price... it's a joke! The best deal in town for sure.
5 stars!
