This place was a perfect location. Walking distance to most of the main attractions. Public transit was just a 3 minute walk away. The hosts were great. Anna and Peter were always quick to respond and were waiting for us when we arrived. They had great information for us and wonderful restaurant suggestions and even had beer for us and sodas for the kids in the fridge. The apartment was very spacious, clean and neat. There were four of us staying 2 adults and 2 kids ages 11 and 8. The kids slept on the couch bed which had plenty of room and was quite comfy. The kitchen was well equipped. When the windows are closed the apartment is very quiet so you don't hear any street noise.
The only downside to this apartment is the floors. They are very squeaky. Every step you take is really loud so if someone gets up in the night it wakes everyone up. Also it was really warm when we were in Prague and the apartment got really hot at night. There is no fan and you couldn't sleep with the windows open because it was too loud.
For the price, location, and quality of the hosts, this is a really great place.
