The location beats everything! So close to everything - everything in walking distance (except for Airport and Belem maybe). The place is also very quite, despite being in the center. Only could hear walking on the floor above in the morning - probably as to thin "walls".
The shower and the rug and sofa could have been a tiny bit cleaner (dust and a bit of black interstices in the shower). But I guess that is also normal to some extend. The place itself is great though! More than you need for a short stay!
