This is a great property with beautiful views across the river. It's in a very central location, just a 15 minute walk from Sao Bento train station, and a 2 minute walk to the river side. Buses/trams to the seafront stop right outside too. We would recommend the Tram Stop restaurant next door for breakfast!
Our only criticism was that it was quite cold (we did visit in Feb) and the property only had a small plug-in heater.
