Lucie is a great host . She ordered us a taxi , met us ( though the flight was late) and explained everything , showed us locations on map , recommended good restaurants and gave some very useful tips ( like to use a tram and not a metro - since we were with a baby stroller - it's much easier with trams) .
Answered all our questions , very pleasant .

The apartment is great . Everything you need is there ( even toys for kids , children bed , chair)
Coffee machine with capsules , great shower . Everything was great .

Location is very good. Few minutes of walking to tram station which takes you to the center in about 10-15 minutes.
Also it's possible to walk ( and we did that ) to the center by foot and enjoy the way .
Near the apartment there are many places to eat and buy groceries .

The next time we come to Prague we will sure book the apartment again.
