For us, it was a wonderful stay :-) For a family of four, it was spacious, very clean apartment with a good view as well. The place is adjacent to the metro Santa Apolino and many traditional Portugese restaurants around.
Carlos is a very friendly and helpful man with a smiley face throughout. He let us check in before time and check out later than expected. So, it was very helpful for us to roam around hassle free without our luggage.
