The apartment is a short(8-9 min) walk to the Castle. It is perfect for one or a couple if you are big on walking as Old Town is a 25 minute walk (pleasant and through a great neighborhood) The only thing to remember is the way back is mostly up hill so wear comfy shoes or taxi/ public transit (right out the door). Bed was not the softest but some prefer a firm mattress-the bedding was exceptionally nice. Room was clean and Shower was one of the best I have had in Europe. Both Tomas and Radek(his colleague) were quick to communicate and be of service if there were any issues. I would highly recommend working with them and staying on their properties. Side note, Praha is WONDERFUL!
