Great apartment in a great location - very close to all the main attractions in central Prague/Old Town. Would definitely stay there again next time we visit Prague, and will recommend it to our friends who will be travelling to Prague next year.
Also, there is a luggage storage place just one block away (just search "luggage" in Google Maps) - very handy if you have to check out in the morning and still have some time to spend in Prague. We stored our luggage there until the evening when we had to take our flight.
