Deluxe room pretty shabby, no fridge in the room, dust in the wardrobe, blinking lights. Old heating unit that didn’t work. For 250eur it wasn’t a very pleasant experience. Also very noisy area. If you have a room facing the street you won’t get any sleep as the party life is crazy on the street. ...
