Berthing - Very good, help from marinieros when arriving. We were in Povoa over a few stormy nights and while the boat moved around, she was always safe.
Security - Access to the pontoon and showers/toilets was using a fingerprint reader, it all worked fine until howling wind and horizontal rain defeated the system and the pontoon access gate was propped open.
Sanitary facilities - Not great, the water in the mens showers was tepid at best, the cleanliness of the ladies was not perfect. Washing machines/dryers available at €2.5 per go.
Cost - €19 per night for our (just under) 12m boat in mid October
