My daughter and I have just spent such a wonderful week at Luis’ apartment. It is supplied with everything you might need for your stay, and allows you to sit in the balcony and relax, watching the world go by. One definite plus for us was the complete blackout roller blinds; I want them on my own house now!
One big advantage is that it is also within very easy walking reach of the Cathedral, the S. Bento metro station and the old town. At night, however, the surroundings are very quiet so a perfect time to sit and watch the lights on the river, and the lights of Gaia.
We discovered that there’s a small supermarket situated on the continuation of the apartment's road, as if heading to town - literally 1-2 minutes' walk away - and most everyday food shopping was possible there; very convenient.
We would enthusiastically recommend Luis’ apartment to anyone wanting to stay in Porto; we just hope that when we visit again it will be available, as we can’t imagine anything better.
