It was great to stay at Studio 77. Communication with Luis was very easy before and during the stay, and he was always quick to respond. Upon arrival, Luis welcomed us with a table filled with Portugese treats, and they were delicious! The apartment is small but cleverly designed, and we found everything we possibly could have needed. We were also pleased with its location since most sights, the shopping streets, restaurants, bars and cafes as well as the river are all within walking distance. Altogether a great place to stay at when exploring Porto.
