We stayed 7 nights in this little apartment and really enjoyed our stay. The host always got back to us straightaway and gave us good suggestions of where to eat. The location is superb.It is a 10 minute walk to the train station and only 5 minutes to the local bus station, where you can catch the bus to Biarritz. We also did a day trip to San Sebastián, which was easy on the train and which the host gave us the information on how to do. There are restaurants right outside the Airbnb and 3 good supermarkets as well as all the shops a few minutes away.
The apartment is very clean, but does get hot and can be noisy at night. We would rebook , if we came to Bayonne again.
