Very central location close to old town square, on the ground floor there're plenty of wonderful food shops, around the corner there's a small supermarket (penny market) and also two shopping malls (palladium - lots of restaurant and food outlet sans cigarette smoke - and kosvo, opposite palladium)
Apartment itself was spacious and clean with all the amenities you needed for a comfortable stay. Washing machine, dishwasher, heated towel rails, stove, tv and lift in the building.
Josef was very helpful with all the info prior to arrival and on the day we arrived. Also with all the touristy info. We managed to go to the zoo and Prague castle with Uber - very cheap.
