Please send me details of 1 & 2 bedroom rentals with sea view in Las Americas & surrounding areas
Why not just look on Holiday Lettings
Websites like Holiday Lettings and Home Away are where you'll find apartments.
On reflection, the OP's question is a tricky one to try and answer.
The apartment complexes that are at sea level in PDLA are Vistasur, Tenerife Royal Gardens and Parque Santiago 1, 2, 3 & 4. But not every apartment meets the OP's requirement for a sea view. For example, we stay at PS2 - I can walk out of the back gate of the complex and I'm on the promenade but we have no actual sea view (not even from the first floor of the apartment.), simply because the design of the complex means other apartments block the view.. On the other hand, there are probably apartment complexes further back from the sea and up the hill, which will have a sea view but may not be particularly convenient to stay in otherwise.
