Lenka was a great host. We had a problem in the check in, the apartment was not clean. I contacted Lenka and within minutes she had a solution- someone from the staff of the cafe came to pick us up and moved us to a bigger nicer apartment for the night (right next to ours), so we felt that the problem was handled in the best possible way.
Except that the apartment was great. Quit, clean, warm and had everything you need. Right under the charles bridge so we walked across the old town by foot everyday.
