Carla's place was absolutely perfect. Only a few steps from the conference center (you can see it from the window) which is great if you are at a meeting - i was able to come back for lunch everyday with my husband. It was very well laid out, even though it is small it didnt feel cramped. The little kitchen area was well appointed and perfect for quick meals and you can buy everything you need from the market below the building. I loved the decor. i know that sounds trivial but Carla has excellent taste and the beautiful blues and yellow were cheerful and contributed to the place feeling open and peaceful to rest and hang out. The airconditioning was perfect in the heat wave while we were there. And Carla herself is very sweet and accomodating. We were in touch throughout our somewhat bumpy trip to Porto and she was very easy to reach. Absolutely recommend this place!
