The apartment is great! Perfect balcony for chilling/smoking. Very quite area with good coffee/food places, supermarket and nice stores for shopping. The tram station is 2 min walking. The apartment is well equipped with all the things you need: coffee machine (with capsules ready for you on the table), refrigerator, tv with netflix, big bathroom and more.
Klara met us for check-in and she was VERY welcoming. She gave us a lot of recommendations and things to do in Prague. Klaus checked with us if everything is OK while our staying, and at the end of the trip we met him for checkout.
I'm sure we gonna visit this apartment again.
