Have only ever spent two days in Corrlejo, so not really qualified to comment on it. All I can say is that we liked it well enough, but it didn't feel like home to us for some reason?
We did spend about six weeks the South before settling in Caleta, though. Very nearly bought in Costa Calma! The beaches down there are just beautiful, and we met some lovely people. However, we don't plan on having a car, and it's quite remote and hilly down there with a bus service that's a bit sparse. Options are very limited for non-drivers in terms of groceries— and oddly, we didn't find much in way of restaurants when we were staying in a hotel and had no eat-in option, either. One or two great ones, but that's all. Finally, the internet/TV service down there is just god-awful, which was the final straw! It's beautiful, but it's for hardier and more adventurous souls than us, who love our creature comforts.
In the end, we opted for the convenience of Caleta. I thought it was much louder and busier here than it really is; by and large, we find there's a good balance of life and tranquility here which suits us. It's got a frequent bus service to the airport and the city shopping, which takes less than 20 minutes and costs under €3. There are two decent grocery stores within walking distance, and they deliver. There are also plenty of restaurants to take your guests to when they visit the larger place you're able to afford because property is cheaper here. The beautiful paved coastal path is really easy to walk on compared to the beach, which is messier and left my hips aching! Best of all, there are decent options for internet and television.
...Finally, though, it's a huge relief to be able to do important things like
Banking, insurance, and legal business in English. I'm happy to muddle along in my halting Spanish at restaurants and shops where the worst thing that can happen is they bring me the wrong food, but I prefer to feel confident that I am understanding and being understood when serious matters are afoot. When buying overseas in a country where you have a limited grasp of the language, I really appreciate having that little safety net for assistance.
We couldn't be happier with our decision. I'm looking forward to a trip down South next month to see the sights, though I am pleased we can
choose to take the longer journey when it suits us rather than
having to come up and down constantly to get things in the city!
