My wife and I loved staying here. The location was extremely central. We were a short walking distance to the metro station and the train station. We could walk to most of the tourist locations in the city. Nuno was a great host, he has excellent food recommendations, if you are looking for some great food you should visit all of his suggestions.
The apartment itself was very clean and as a bonus the building has a lift that is useful for getting luggage in and out. The bed is also a king size bed which I think is pretty rare in the area.
