Maria is an amazing host and the apartment is stunning with an awesome balcony. This place could easily sleep 5 and you would not even feel crowded. Proximity to the beach is by far the best asset.
Just be warned, in the off season (we visited in the end of November) there are few open amenities nearby. On Sunday, no restaurants or cafes were open. Just the grocery store for a couple hours. But, if you are into a quite stay, we had beach walks all to ourselves.
