Jaroslav's place a great stay in Prague. The area is full of restaurants, cafes and bars, yet it´s not that busy. Apartment is well located, with a fast and easy connection to the city center.
It´s nicely refurbished, clean and with all needed appliances, even if you stay a longer period - if you plan working from there though, make sure you have a fall out internet connection, as the wifi works well, but the signal strenght is different in each corner of the apartment.
All in all, Jaroslav and his colleagues provided great service and communication and i would gladly stay in one of their apartments again!
