We had a very good time at Catherine's apartment! The apartment is quite small but good for 4 people. The sofa bed is good and the photos are truth to the apartment. It is located very close to the metro so it was easy to go to the main attractions. Catherine is very easy to communicate with and she was very helpful and quick in replying to our queries. She sent us very detailed informations of how to use everything in the flat and how to get the keys! I definitely recommend it!
