My stay at Sabina's place was fantastic. It's pretty much exactly what I'm looking for when booking a private apartment/house. While cleaning from the previous guest they let me drop my bags off early, checked me in and gave me a great rundown of the area, and then were gone so that I could get on with my stay.
The place was very clean and comfortable, and the location can't be beat.
Despite Old Town Square being a very touristy area, there's a surprising amount of high quality restaurants all within walking distance.
If I'm ever back in Prague this is where I'm going to want to stay.
