The location is great, especially if you want to spend time at La Concha beach. It is a 5 minute walk to old town, centro, etc.
The building is secure and has a few amenities.
The only issues we had were the cleanliness and air conditioner. The apartment could have been cleaner, we wiped down surfaces and found dust and dirt, swept the floor twice to clean it. Also the air conditioner did not work. I admit the missing does not include it, but our host showed us the remote and said it was available. There was a heat wave during our stay and the apartment was incredibly hot. The air conditioner works have made our stay pleasant but numerous text messages with our host didn’t get the problem resolved.
