My experience matched that of other reviewers.
Joana’s apartment is in the pedestrianised shopping streets around the cathedral. It is very close to the river and to the covered food market. Being on the top floor and at the back of the building, it is very quiet. The terrace is a great place to relax.
The apartment has a large bedroom/sitting room, an excellent large bathroom and a small well equipped kitchen. It is within easy walking distance of transport, restaurants, shops - including supermarkets - and the many sites of Bayonne. The travel time is short for trips to nearby Biarritz, St Jean de Luz and many other places that I would have liked to visit.
Joana made everything straightforward and happily accepted my late arrival time. If I have the opportunity to visit Bayonne again this will be my first choice of accommodation.
