We really enjoyed our stay at Manuela's apartment. It is located in a really central part of Cadaques and close to everything you need, only a short walk to the beach and seafront with wonderful restaurants.
The one thing to be aware of is that parking in Cadaques is difficult in the summer and having a new rental car we preferred to use the public parking which cost about 22 euro per day.
The apartment is great and has everything you need for a family of four, Manuela was very helpful and stayed in touch throughout our stay even though we did not meet her personally.
