Visited the place in Jan 2022.
the location is amazing. cozy, beautiful street with cool bars and Cafes nearby. in the city center but doesn't feel touristic as many other streets in Prague.
The apartment itself is great. very comfortable and beautiful from the inside.
had one issue which was the heating - it was a bit weak and it was a little cold inside. only relevant for those that come in the winter.
I highly recommend Daniel's place. had a wonderful time there.
