The apartment is extremely nice, clean and in a really good location. Alena always replied fast to our questions (before and during our stay) and gave a lot of useful information about how to get to the apartment and what to visit etc.
Even when our flight was over one hour late and Alena therefore wasn't able to welcome us personnally she really fast organized someone else to give us the keys and show us the apartment. So everything went perfectly fine :)
We enjoyed our stay a lot, Prague is a beautiful city. We absolutely recommend the apartment to everyone!
