Thank you very much to Lukas, Michaela and Bohumil for their welcome !
We had all the information we needed. We found easily the flat thanks to Michaela. Then, Bohumil gave us the keys, explained a lot of nice and interesting info, showed us through a Prague map all the cool places to go. Special thanks for his advice concerning Liberica Cafe, we loved so much having breakfast there !
Thank you too for the attention with some biscuits !
The apartment was really like the picture : nice, clean, well equipped, towels and bedsheets included. It was pleasant to find a hot room when it's so cold inside.
The street is silent, and the flat is perfectly located, very easy to find our way to go out or to go back home.
All was perfect !
Just a few details to improve : the toilet goggle has a broken side, and in the bathroom, there is a little water leak (you can hear often a drop noise during night).
Conclusion : our trip was excellent, it was a pleasure sleeping in this apartment. Thanks to our hosts !
