Okay so alex's place is a very standard airbnb but of better quality than what I have seen in Barcelona or in Venice. Very very centrally located, right outside cafe louvre and basically all you need to do is just start walking and go wherever you want to do. His friend David gave us some great tips for going around the city and helped us get along just fine. When I come back to Prague, I am definitely staying here again! Recommended that you stay at this place for sure!
