We stayed here late June - early July 2018, a family group with 3 older teenagers. The apartment is clean, and has all you need for a very relaxing holiday, we didn't hire a car, you don't need to. There's a supermarket a short walk away, and all the restaurants, cafes etc you could need right on your doorstep, yet the area is not noisy. The pool area is clean and was never busy, we often had it to ourselves, all communal areas are well kept.
The apartment itself was a pleasant surprise, the photos don't quite do it justice. It's spacious, and has everything you could wish for (although a few dishwasher tablets, a bottle of water, and a couple of teabags left for guests would be appreciated). The air con is great, but the breeze means you shouldn't need it much if the balcony doors are open. The shower is powerful, but has a mind of it's own! The English TV channels are hit and miss reception wise, but you won't need TV, just go out on to the balcony, its wonderful, the view is amazing.
Ana, the lovely key holder was waiting for us at the apartment block entrance door, and she was a welcome sight when we arrived, it's always a relief to see the property actually exists, and you'll be let in! However, be aware, there's a knack to opening the building door, it seems to be a longstanding issue, you'll get used to it, but first time you'll think you have wrong key. Only one set of keys provided, which was inconvenient.
I wouldn't hesitate about recommending this apartment (and Quarteria) to anyone, and would definitely book it again.
