We stayed at Catarina's from May 24th until May 31st, and we could not have had a better time. It was just my wife and I, but the apartment could easily and comfortably accommodate 6 adults. The neighborhood is quiet. There is a little supermarket only a few blocks away (we had a car, which I suggest just for getting around the island and seeing the sights). The kitchen is not large, but it works very well (I cooked dinner two nights of our stay). The place is kept very clean. There is a washer and clothesline for your clothes. There is also a lovely back patio with a wonderful view of the town and surrounding countryside. The location was perfect, allowing us to get into Punto Delgada in a matter of minutes but without staying in the city center, where parking can be an issue. The apartment also has an excellent location for getting to sights on either side of the island.
I should also say that our host, Catarina, and her husband were just lovely. There is a lockbox with the apartment key, which allowed us to check in at our convenience (and Catarina let us check in earlier than planned, which was very generous and helpful). She then came over to meet us and give us tips on restaurants and sights to see. She was very friendly and very respectful of our space and time. Perhaps most importantly, she and her husband were just a phone call away to handle any issue that arose. We really hope to stay at her property again. Five stars!!!
