Ondrej's flat is ideally located near the main square and Karlovy lázně (the popular dance club). Public transit is accessible, though not necessary. The flat is small but clean with basic amenities provided. Be aware that the bed is in a loft area with access via a wooden staircase, the shower is in the kitchen area (though curtains are provided for privacy), and the WiFi is a bit weak in the flat.
One great additional touch are a variety of brochures and guide books available in the flat, including a wonderful pocket guide book for those still looking for ideas or maps of the area!
