We (four people) stayed four nights in Alvaro's apartment in Porto. It was one of my best AirBnb stays so far. Everything was sparkling clean when we arrived, and Alvaro was there to greet us with fresh baked goods and explanations about the city. Alvaro himself is a fantastic host, checking in with us regularly if we needed anything.
The kitchen is well-equipped and the rest of the apartment just as described (two bedrooms upstairs, one with double and one with two single beds). Heating and AC are available for use and wifi works perfectly. I recommend this apartment very highly.
