This was my second time staying at Alena's, because she is such a warm and personable host. Despite leading a very busy life, she was constantly checking in with me -- she made me pasta, offered me tea and coffee, and was full of advice about Prague. Once you figure out the shortest way down the hill (take the stairs through the park), her house is actually a very short tram-ride to Andel, one of the cooler places in Prague to eat and shop. Highly recommended.
