We liked Pepa's apartment a lot! Pepa herself is a very nice and welcoming host! She thought about all details of our stay and made it extremely comfortable. I really recommend Pepa as a host, believe me you will enjoy your stay. I especially appreciate the New Year decorations that helped to keep holiday mood.
As for the apartment - it has perfect location, you are next to the Cathedral, embankment, shops and restaurants. The apartment is nice and spacious. The kitchen is well equipped. If you have a chance, book this apartment for sure :)
