The Luamar won't be beaten for location, being directly on the beach with stunning views and a great outdoor pool area. Against my better judgement we paid the supplement for sea view apartment and I have to confess it was brilliant and completely worthwhile.
The breakfast was really good, staff friendly/efficient and a lovely local restaurant across the road.
The biggest disappointed was the apartment itself (1 bed)- extremely small, very dated and no air conditioning in the main room (where our children were sleeping). Ideally you'll need 2 bedroom apartment for a family of 4.
Overall we had a great time and it's tough to knock the hotel on the basis of the room as we spent so little time there....however, whilst the location is 5 star, the hotel is 3 star at best.
Porto Santo is a delight.
