Availability of units on Block 3 is still quite good, many investors tend to stick to Saidia as its well known, however Port Lixus in my opinion is about 12 - 18 mths behind Saidia in terms of construction however this is reflected in the prices, more info on La Plage can been found at the following website;
La Plage Port Lixus Luxury Resort and Hotel In Morocco
Any questions feel free to post..
