My husband and I spent 4 nights at this property. This is a great spot, with good value. It's right near the Dancing House, with less than a half hour's walk to the main sights in Prague.
Zeb was welcoming and accommodating on checkin. He left us with a thorough map and some recommendations.
The bed is comfy and bathroom/kitchen were perfect. There's a supermarket (Albert) right around the corner and coffee shops/restaurants galore. Be aware that the property (an old monastery building) is very dark at night and you need to climb up 2 levels of stairs in the dark. There are some motion sensor lights but they aren't reliable - so have your phone flashlight with you.
