We had a perfect stay at Miguel's flat which is well located and conform to the pictures!
The neighbourhood is really nice, peaceful, full of good restaurants (try some Rua da Esperanca), it's 15minutes walk from Bairro Alto and the mercado at Cais do Sodre.
The flat is perfect for 2, the bedroom is quiet and fresh. Also, good point is that you can have nice breakfast on the terrace! Don't hesitate!
