Very friendly and communicative host. The apartment is located in a nice and quiet area and surrounded by some interesting places to have breakfast or dinner. If you're up for a drink in the evening you'll also find plenty of bars to choose from.
The apartment itself is beautiful and spacious. Nothing was missing on our arrival and we enjoyed our stay.
The old city is within walking distance (approx. 20-25min) but also very near to subway stations if you prefer to move around more quickly.
Definitely recommended host and location for visiting Prague.
