We were unfortunately not lucky with the weather during our visit, but otherwise our stay was excellent.
The junior suite was lovely, large and offered a beautiful view of the bay. Staff were excellent throughout. We enjoyed the outdoor pool for a bit, although it was rather cold and then enjoyed the small indoor pool as well. Services were rather restricted due to Covid, but the hotel did their best to make things works and I imagine it's only better in normal times. Breakfast was very good as well. At over EUR200pn it definitely is on the pricier side, though.
The building is actually rather ugly on the outside and much less attractive than the one it replaced. Why on earth you'd build something that would sit better on a business park in one of the nicest parts of Estoril is beyond me! The inside is a different story and they did get that entirely right.
