Pleasant flat in a fantastic location for bars, restaurants and nightlife. Has all the facilities you need, and check in was straightforward.
The only downsides were the 30 euros we were charged for checking in at 11.15, and that the tone of the information booklet made it a bit difficult to relax and enjoy the place (ie long lists of things you could be in trouble for such as talking after 9pm, and lots of requirements for cleaning etc before checking out), and that the 3rd bed wasn't made up as requested.
