We were a group of 5 adults and had a great in this spacious appartment. Sarah is a very welcoming and helpful host - even though she had to wait quite long for us due to a train delay.
The location is really good: there is a small super market around the corner, 2 more minutes and you´ll be at metro "Trindade" and the city centre is about 10 minutes by foot down the street.
All in all we can only recommend this flat and Sarah as a host :)
