We stayed in Frederico's Oceanview Penthouse while attending a friend's wedding and had an excellent experience. We were travelling with a small baby (<6 months) so we wanted somewhere with a cot, baby bath etc and this was all provided for us which made our trip much easier.
On the night we arrived we had an issue with our transfer and didn't arrive until approx 1:30am when we were due to be there at 11pm and Frederico was very patient and accommodating, waiting for us until we arrived and showing us around the apartment.
During our stay he responded to our questions via WhatsApp very promptly and offered recommendations for the area as well as helping to organise our return transfer to the airport.
The apartment is really nicely decorated, very comfortable and in a nice quiet area with plenty of restaurants and amenities nearby. It's also really easy to get to with the train station only about 3 minutes walk away.
