The many positives about our stay: top quality apartment and equipment, very spacious, very quiet. Great swimming pools, good access to Marbella old town, (an hour walking, 1.18 Euro/person on bus - 5 minutes walk, 11 Euro taxi), high speed reliable Wifi. Great patio area for lunching/late night drinks.
Slightly disappointing factors (all pretty minor) - the nearby beach restaurant had pretty average food (in our opinion), check-in/out procedure was a little disorganised, TV was available, but was only usable with the Chromecast device we'd brought with us.
As I say the many positives outweigh the minor gripes, and I would definitely recommend the property.
