The space is great - huge rooms with great air flow. The weather was very warm when we were there but the space stayed comfortable thanks to a couple of fans and huge windows. Our kids loved playing inside so much it was hard to get them outside sometimes. Location is hard to beat - short walk to St Charles Bridge, the castle and Kinsky Garden (great for a hike or hilly run with a great view + playgrounds for kiddos). Vaclav was very kind and accommodating with great communication. Don't know when we'll return to Prague but will definitely see if Vaclav's space is available when we do.
