First of all, Slavomir was incredibly helpful, informative, flexible, accurate and he replied very quickly, communication was very very easy with him.
I did not spend there too much time, but the flat's location was more than perfect, everything was close, public transport was available easily. The accomodation was clean, comfortable and cosy. Every needed equipment is available for staying long term as well.
I am sure if I will go to Prague again I definitely will check if it is available or not. Highly recommended! Thank you, Slamovir!
