This was an excellent place to stay! Zumaya is a small town so there is a lovely feel about the area, amd I would recommend it if you need a place to relax and enjoy a quiet time.
There were things to do like hiking to the nearby towns and also taking a boat cruise, although I recommend booking as soon as you can because mine got cancelled 2 days in a row due to bad seas (they are concerned about passenger safety and that is good!!).
The view from Juan Luis' apartment and the room is fantastic and since the weather changes so quickly, you can watch it all from the comfy chairs.
Sometimes there are festivals and since the apartment is right in the main street, it can be noisy - usually this falls on a Saturday night. There was one while I was there and it was noisy until the late hours of the night, but that's Spain and as long as you dont have to get up at 6am, you can sleep in on Sunday!
The apartment is spacious and comfortable and Juan Luis is everything you'd want in a host.
