Emil and Olga's apartment is a great place to be and possibly the best choice in order to discover Prague: It's located centrally and you basically don't even need public transport. Nice cafés, shops and restaurants are nearby within walking distance, too. The flat was really nice, clean and spacious and provided everything we needed - it even had a dishwasher in the kitchen.
Communication with Emil and Olga upfront was very easy and when we arrived, they gave us a lot of information regarding what to do and see. Whenever you are planning a trip to Prague, I can only recommend staying here!
