My friends and I spent a few days at Lanka's. David was our primary contact. We arrived at different times and David was able to let one of my friends in a little bit earlier than the posted check-in time. He gave my friend very detailed information about the flat, how things work, and the community.
The apartment was just what we needed. The beds were comfortable. The kitchenette amenities were just what we needed. The studio is furnished with plates, cups, cutlery. There are plenty of outlets and extension cords. The room had heat and the water heater was large enough to have hot water for 3 women to shower one right after each other.
The apartment is very close to the main train station which was a plus for us because we had an early morning train ride out of Praha.
I would gladly recommend this as a place for others to stay when visiting Praha.
