Good points: very good location, clean and inexpensive, with a friendly assistant to welcome us when we arrived after midnight. A generally very relaxed place. Happy to let us leave bags after check out so we didn't have to carry them around all day - thank you!

Not so good points: the accommodation was pretty basic, cheaply furnished and equipped, and poorly maintained. There's just one (very small) toilet, accessed from the kitchen space, and a separate bath/shower down the corridor. The three big bedrooms seemed to each sleep around three people so, as a multiple occupancy, you could be sharing the limited facilities with up to eight others.
Instructions for getting to the accommodation were out of date, but it was still quite easy to get to with a bit of help from the airport info desk.

Altogether we had a very nice time in Prague, but this may not be the accommodation for everyone.
