This apartment has everything you want to have both for short weekend or a 5-day stay. We stayed me and my mum for 3 days (2 nights). We had a room each, and the beds were both super comfortable.
But the main thing about this place is 1) the hosts: making everything for you to feel at home
2) the cachet of the apartment: it´s an old building and the flat is decorated with a lot of taste: simble but chic. There is plenty of light and a nice view over the Taje when you look through the window...
Cais do Sodre, the location, is very good: every interesting and lively place is within walking distance.
Definitely convinced me to stop using hotels in the future...
Thank you both Ines & Antonio, we had a great time in Lisbon!
