We had such a pleasant stay for two nights with Columba in her delightful apartment just up the hill in the Aniguo District. From the apartment, it was only a short walk downhill to the Ondarreta Beach where I swam in the cold but beautiful turquoise water. There is a bathhouse on the beach with hot showers, towels, lockers and WC.
When I had asked Columba about beach towels, she did not provide them, but suggested an Asian market that sold them. Unless you will be staying more than a couple of days and wish to swim, it makes more sense to just pay a couple of Euros and use the bathhouse facilities.
The common areas, bathroom and two bedroom rentals are beautifully decorated with mementos and artworks from Columba's own travels. The delicious breakfast she serves out on the balcony overlooking the harbor is a true treat. We stayed in the smaller of the two bedrooms which has a balcony overlooking a park-like empty lot. It was very pleasant to listen to the songbirds in the morning.
The big white male cat that oversees the apartment and permits Columba to tend to his needs and desires, I found highly amusing. Also, the most stubbornly aloof I've ever met. We didn't stay long enough for him to warm up to us, but apparently, had we been there another day or two, he would have allowed us to give him strokes. I did discover that yogurt is his weakness, so if you try offering him some of your breakfast yogurt, you might speed up the process.
Columba herself is very warm and kind. Perhaps due to limited space and her esthetics, you won't find stacks of tourist information. But her English is excellent and she is very willing to provide whatever information you request.
Staying in the unique environment she has created was a very comfortable and pleasant experience.
