Great location! I love the Vinohrady area. There are a few amazing parks out there, lots of restaurants and nice cafes to stay during the day. For me it's the best location in Prague. Price was very competitive as well. The place was clean. I haven't met the owner, but communication was clear and polite.
They were so nice and bought a new quality office chair for me. So the place with its fast internet connection and office chair is highly recommended if you work (thanks to Corona ) from home. It's nice if an owner adapts so fast to the clients :-)
