I stayed at this property twice: a couple nights at the beginning of my trip and one night at the end. The design was very modern and serene. The folks at the front desk were very friendly and accommodating. When I arrived, it was too early for check in, so the gentleman at the front desk invited me to put my luggage in a secure closet, gave me a map and suggested some places to visit as well as a local bar to get some breakfast. The included breakfast buffet was excellent with fresh bread, pastries, eggs, bacon, etc. It's convenient to the marina/downtown area as well as the gardens, Parque Atlantique, etc. I felt safe walking solo. And the aroma of bread baking from the bakery next door was intoxicating! Reception even arranged a taxi for me to get to the airport both times.
My only issue with the hotel was when I stayed the last night. I was in a room across the parking lot (opposite reception). My bathroom smelled of septic/sewage. Everything looked clean, but it was somewhat unpleasant.
That said, I'd certainly consider staying there again if I find myself in Ponta Delgada!
