I would definitely recommend this apartment. The location was great, interesting sightseeing spots and a huge shopping mall (which offers pretty cheap parking by the way) are close-by. The apartment itself is nicely decorated and charms with it's minimalistic vibe. When you wake up in the morning the smell of the bakery downstairs greets you on the balcony. Only downside: It's quite noisy (especially the eager seagulls flying around) at night.
Although we did'nt meet Mário in person, he was really nice and quick in his communication and answered all of our questions we had.
