Although I didn't have a chance to meet Karolina in person, I'm happy to have chosen her apartment to stay. It is very cosy, light and welcoming. Coming back from noisy city centre to calm neighbourhood of our temporary home was a pleasure. Minor imperfections due to slight redecoration didn't make us feel uncomfortable at all. We kept in touch with Karolina via mail before, during and even after our stay in Prague. Karolina sincerely wanted the trip to be as full of impressions as possible: she provided us with several maps with marked sights, described possible routes around the city and recommended bars and cafes approved by a her as a local, which is much more valuable than recommendations in many tourist guides. So, with Karolina's remarks we were able to improve our itinerery significantly.
I'd like to say additional Thanks to Karolina's mother, who met us on Karolina's behalf, gave us even more advice about safe stay in Prague and was ready to answer any questions during our stay.
All in all, if (or more likely when) I come back to Prague, I know who I will turn to looking for a place to stay. Thank you, Karolina :)
