Perfect stay in a perfect location.
Communication: Excellent. I wrote before booking to ensure a late arrival (0100) would be okay and they were more than willing to accept us. We did arrive at 0100 and we were shown our room and allowed to get some much needed rest. There was communication here and there before our arrival and any question we had was promptly answered.
Location: Can it get any better? On the Ribeira with a view to the Luis bridge? I mean...The location can be a bit of an issue if you are a light sleeper. The noise does on the river does not continue very late (nothing past 0000-ish). But if you want a midday nap, or to go to sleep a little earlier there might be a slight issue. The noise is not overbearing, but could affect you.
Room: As described. Great bathroom. Working iron, hair dryer and great Wifi. Bed is comfortable enough, not too hard not too soft. Amazing views from the windows. Only up a flight and a half of stairs (and wide stairs), so nothing strenuous about reaching it. Although there is not a kitchen, there is a fridge to help keep stuff cold. We didn't need them, but there are fans and space heaters depending on the weather.
