Location, location, location, and a really cool place to boot! Very quiet and comfortable for four.
We were met at the door and went over some rules and signed a contract that was basically a promise to leave when we said we would and not trash the place.
Back to location... We were one block from town square and within easy walking distance of everything we wanted to see, including Charles Bridge, Prague Castle, Old town, and more. No end to food, shopping, live music on every street. No messing with confusing public transportation meant that we had more time to explore the beautiful city.
This was one of four B&Bs we stayed at during our vacation and by far the best. It had a washing machine (no dryer), and really A/C in the upstairs bedroom and on the main floor.
Wifi was available and reliable, and everything we needed was there. The beds were comfortable and even the pillows were top notch. If there was anything that approached a negative, it was that there were really no windows to see out over the streets. They were all skylights or too high to look out of.
We would recommend this place to anyone and really enjoyed our stay!
