The apartment was just as described: perfect location with an incredible view, tasteful & modern decoration, clean. Marcelo & Marcelo Jr were perfectly on time for the check-in, with a nice touch (local pastry & a glass of Porto wine, plenty of tourism information). Overall a very good experience.
If like me you come in October, be aware there is no heating in the apartment, so it can be a bit cold and (being by the river) humid. However Marcelo told me he would bring a couple of electrical heaters for the next visitors, apparently they were just removed for the summer.

The main room, with the lovely view, is both a bedroom (queen size) and a living room (sofa, TV, table & chairs) with a tasteful & modern decoration. There is another bedroom with two single beds but no window. The kitchen is small but functional. Although the apartment can host up to four people I'd say it is ideal for two (e.g. a couple).

Even though you should enjoy Porto instead of watching TV I should mention the flat screen is very big and I could even connect my laptop using HDMI :)

Bottom line - slightly pricey for Porto but worth it. That view!!!
