What a wonderful space Lenka has created. The space is gorgeous and the area one of the most romantic places I have ever been to. It is great to be at 'the other side' of the river, yet everything is easy to get to on foot. Great excuse to walk the Charles bridge many times.
One thing to know. The cafe downstairs is very popular and with nice weather people gather in the little courtyard at the back of the building and also outside at the front. That means that when one has the windows open upstairs, it is noisy until the cafe closes. Once the cafe closes and the customers are gone, the area is extremely quiet. During our stay the cafe closed at 10 pm (22:00) so it wasn't a problem and when it is colder it shouldn't be a problem at all.
