Overall, we enjoyed our stay in Callao Adeje apartment.
The pool was amazing and a few steps away. You must be quick though since people reserve the sunbeds with their towels! A nearby black pebble beach was amazing as well. Much better than sand, since sand gets everywhere. We went twice. Very relaxing to sit near/under one of the umbrellas.
Nearby restaurants were nice. We went to Restaurante El Ancia (amazing seafood), the Italian corner (nice pizza/pasta), The Terrace and Nebula Restaurant (ate 2 days in a row amazing selection of food, I had the fillet steak amazing!). You must be quick since most restaurants close the kitchen around 9pm, and some you have to pre-book since they get busy.
We went to the rooftop bar at Mynd hotel. You can walk in and take the lift to the top floor. Very nice views. Rooftop pool can be used, and there is a grass area which was very nice.
We hired a car for a week so drive to the bigger Hyper Dino supermarket, and fa few other markets nearby (Costa Adeje, Los Cristianos, they were ok). Also drove up to Los Gigantes. We went to El Duque beach, where we ate at Luuma restaurant, very nice sandwiches. And one morning were taken out on a boat trip (booked through Maxim Excursions) and say some pilot whales which was quite cool. No Dolphins though. We also visited the SIAM shopping mall for some rebajas.
A couple of downsides to the apartment: There was no AC in the bedroom. It was very hot at night whilst trying to sleep. So unfortunately, we didn’t sleep well. There was an AC in the main living room which was quite effective. We didn’t turn it on through the night since I was told I would be charged for over-using electricity, which was not made clear to me at the time of booking. So avoided using it whilst sleeping. Secondly, after using the washing machine, there seemed to be an influx of cockroaches from the sink. Since my partner is terrified of them, this caused some stress in the evenings in the last few days of the trip. We made sure to mention to Fabienne, who was really helpful throughout the trip answering on WhatsApp.
That said, definitely worth a visit and hire a car to visit the neighbouring beaches/areas.
