Lucie is a great host. She was very punctual and reacted immediately as the wifi stopped working. It turned out to be a general problem in the whole area of Prague. But Lucie's husband found the info quickly and informed me.
I am very familiar with Prague so I didn't need any advice from Lucie but she had quite a lot of information material available.
The flat is very comfortable, has a lot of light and was super clean.
The location is great. very close to metro and a tramstop that gets you to quite a lot of places without having to go underground. Also great: the vicinity to the airport.
