Great location, great communication, and a good amount of space. It was a fantastic base from which to explore Prague, and as an added luxury for Poke-nerds, it's inside (and surrounded by) Poke-stops! Nice if you have kids/are a grown-up one.
Can be noisy in the mornings (even Sunday) with road-works but that seems pretty common in Prague atm and won't always be an issue. Highly recommended and we'd be back.
