I have already recommended this place for a friend who lives in Prague, so he can recommend it further to everybody visiting the place. This is maybe the best testament of a good experience!

Not-too-costly, and professional, I would say. Small things like having several bags of coffee and tea for you, and having a couple of beers and water bottles in the fridge for you when you arrive, are things I appreciate. Even the toothpaste and shampoo was there for your use. Host was helpful in any respect.

More important are the larger things. The place is at the best location in Prague if you are in for living a 10-15 mins walk to almost everything. From the old town square with tourists/bar crawls or to the ferries laying sleepingly by the riverside with cheap beer and Czech people, gathering up on the streets when the weather is fine. Also the Monastery and Presidential building is within walking distance if you are fit enough for some upwards walking.

If you look for a cost-efficient place to stay, that will exceed your expectations, I think you found it. If you look for a 4 star hotel, you haven't found it, but this is an excellent option for anyone that'd like to have a decent experience for a good value!
