Elena's apartment is huge, bigger than the photos indicate, and has everything you may need for a short or extended stay in Prague. The price was very reasonable, especially since we were able to cook and eat-in whenever we wished. Since we were 2 couples, we used the sectional sofa as a bed, but it was extremely comfortable. The arrangement of the apartment allows for complete privacy for both couples. It was great to have a washing machine, too.
Elena was able to give us transport to and from the airport, and gave us lots of info on what to do in Prague and Czech Republic. All-in-all, highly recommended!
