Danilo's place is in an ideal location at the base of the Charles Bridge. However, if you leave the windows open at night (because there is no air conditioning), you should be aware that you may hear a lot of noise from other tourists wandering around - we had that issue until 2AM on a Saturday night. If you close the window, it is indeed soundproof. The apartment is stylishly decorated. Danilo was easy to communicate with and responded promptly. Check in was easy and he provided information on how to get around the city as well as other tips, brochures for tours, books about Prague, and excellent restaurants to try. He accommodated our crazy travel schedule - and this was much appreciated! The only other issue is there is only one set of keys. (If one person wants to leave the apartment, their partner must also.)
