Its an amazing and lovely apartment.
Firstly, the location is perfect, just near the old town. And it has three rooms which are enough for more than 5 people to live in. Our group has 4 people so its too big for us.
Second, the apartment is very clean and comfortable. We feel pretty relax for 4 days.
Third, it has complete facilities for showering, cooking and washing.
Finally, Lenka, the landlord is so sweet. She arrange us to check in earlier although we can't reach it in time. And when we have some questions she will respond us ASAP.
Above all, its an amazing journey to live in Lenka's apartment in Prague. Hope more lucky guys could have this wonderful experience.
