Overall a good place, families with children both young and older children will like the pool as it is so big. My son loves tennis so he was able to play every day which was great. We enjoyed being able to walk to one of two little coves ("calas" in Spanish) that were 2 or 3 minutes' walk away, the snorkeling there was great. The beach at Tamariu if you like beaches with sand and amneties like cafes, is about 20 minutes' walk (and I'd recommend walking as parking is tricky), a bit less if you can locate the steps goinig down, several sets of them.
Communication with Javier was ok although there could have been more detail, e.g. about which apartment it was and which of the two electric gates the key fob opened. However, there is a lovely concierge who lives on site, who sorted it all out for us. The off-street parking in your own spot in the compound was great.
The apartment is on the small size for two adults and two children and I think it would be tight with 6 people if the living room sofa bed was used. Balcony very nice with pool, tennis, mini golf (all free) and sea view. Because there is an on-site concierge, even if some people get a little noisy later, they are soon spoken to and the nights are reasonably quiet. Because the apartment is on the small side, it can be difficult to get air in during July / August and there was only one fan, ideally there would be one for each bedroom. Mosquitos were a minor issue, maybe bring some spray if they bother you.
Probably the biggest area for improvement would be the bathroom. The small size cannot be helped, but one of the shower glass panes was missing, meaning that every time you took a shower, water inevitably leaked a lot. This then led to bath mats and other towels getting soaked in the mop up. The problem was compounded by the broken wall fixing for the shower head, which meant you had to hold the shower head in your hand the whole time, and the slow drainage. I communicated the problems to Javier and he asked me for the shower tray measurements, which I gave him. He gave signs of wanting to fix it but didn't during the two weeks we were there. I have stayed in properties in England and Austria mainly but certainly in those two countries such a lack of maintenance would not be acceptable. And I suspect that some of these defects were fairly long-standing looking at the airbnb photographs, where you can clearly see the shower head is not attached.
This is a minor criticism as we still had a great time due to the location.
