We took a diversion from our trip to Austria for four nights at this apartment in Prague during mid-November. The apartment itself is located on a residential alley next to a large historic church, and is a 3 minute walk from old town square (basically where Charles bridge connects). There is an ATM right next to it and a million good restaurants in walking distance. The alley is relatively quiet at night, safe, and has an outlet to another main street on the other side.
Check in required a key from a box 2 minutes away, and the hosts provided perfect instructions for it. The apartment itself is spacious, comfortable, and plenty warm for the autumn weather. I cannot say enough good things about the location!
We had a wonderful stay and highly recommend this apartment if you are visiting Prague in any season.
