The description of the Loft matches the reality.
My wife an I were there with our three kids and my father in law for two nights at the beginning of April.
Lucie is a warm-hearted host who responded quickly to our messages.
She gave us helpful advice about restaurants and sight-seeing.
You can take Tram 22 to go downtown while seeing a lot from the city already.
We switched to Taxi, because we felt it to be more convenient with the kids.
Traveling from the city-center to the Loft costs around 250 Krone which is around 10 €.
Next time we visit Prague we will stay at one of Lucie's Lofts as well.
