My husband and I really enjoyed our stay in this beautiful apartment in Porto. Luís made us feel very welcome, meeting us from the station and giving us a complete (and thorough!) guide through everything there was to see in Porto - some wonderful recommendations which came in very handy, particularly when staying is such a big city.
The location of the apartment is brilliant, right in the historic center. We were a bit apprehensive that it would be really noisy being so central, but the double-glazed windows did wonders at shutting out the noise of the street.
Porto itself was a really vibrant city, we went for the Primavera Sound festival (which was excellent!) but still managed to fit in quite a bit of sight-seeing (and lots of Port tasting!). Would definitely like to revisit one day, if only to tick off more of Luís' recommendations!
