I had a great stay at Josef's apartment. While i only met his colleague when i arrived, Josef has been very helpful and was proactively informing me about everything i needed to know, and things i did not know i needed but definitely did (tips for supermarkets, vegetarian restaurants, etc.:) The place was as nice as on the pictures, and very clean. All in good condition, in a safe building and street. It is a bit unusual to enter through a souvenir shop (especially at night when the shop is closed), but this was not a problem at all, just a curiosity.
