Josef is really kind and helpful, gives you lots of advice and indications. Also he is really approachable. We arrived to Prague really early in the morning and he helped us keeping our luggage until we could get in the apartment. He gives you discount for breakfast in a really nice and cool place which is less than 5 min walking from the apartment.
The apartment is amazing and it is exactly the same as in the pics, really clean and with perfect location, less than 5 min walking to the old town square, also I have to say in the street of the apartment you have plenty of places if you want to have a drink or something to eat.
recommend the apartment and Josef 100%
