The apartment is large, central and has a beautiful covered terrace that looks out onto Easo Plaza. From this apartment you can walk to the beach in 8 minutes, take the bus to other towns along the coast in 5-10 minutes, and get to the old town in 10 minutes. The plaza it is in front of has a number of bars and restaurants, and there's a supermarket, bakery, and pharmacy all within 1 block of the apartment!
One thing to note is that because of this central location, it could be loud. At night we often heard people yelling or partying, and early in the morning construction noises began. If you're a particularly light sleeper this may be something to consider - one of the people in our group had issues sleeping due to the noise and had to adjust their sleep schedule accordingly.
Jon was a great host and was responsive and friendly, even when we asked about things unrelated to our apartment (recommendations, etc.).
One note about the AC: there is one portable air conditioning unit, but to use it you need to open a window/terrace door, since you need to leave the exhaust pipe (in the back) outside. You can try to close the door as much as possible, but this does mean that some hot air will enter from outside at the same time as you are trying to cool the house. We tried using it and ended up giving up, because we visited in May.
