The apartment was great, everything was clean, we had plenty of utensils in the kitchen and bathroom to use, the apartment it has double windows which is very helpful to keep the temperature and as sound isolation.
The ubication is very good, its just on the border of the center, in just 20 min walking you can be in Carlos Bridge, above that, its just next to some interesting buildings as the National Museum and the State Opera which gives you great views.
The comunication with Lukas was perfect, he helped us with all the doubts we had about Prague before our trip.
I highly recomend this apartment
