This flat is truly superb with its very uniquely designed space and the balconies on both sides of the building. And precisely because it has such a great potential, it was puzzling and slightly disappointing to see that it is not run properly. For example, the level of cleanliness was quite low - there was beard hair in the bathroom sink area and bread crumbs on the dining room chairs; the surfaces of the tables, including those at the main terrace, were poorly wiped; and not to mention a stinky vitrine for glasses. We were also unpleasantly surprised that the host company did not provide basic supplies (washing machine powder, dishwasher tablets, a clean sponge for doing the dishes, more than one cloth for drying the dishes, etc.), as well as the basic welcoming pack comprising coffee, tea, and possibly wine (because we are in Porto, a city famous for wine!). Having complained about this, the host company delivered expressly the requested items.
For future reference, it would be great to see that the host company invests a bit more into decoration (the current one is with not much taste) and kitchen supplies (e.g., cleaning sponges & drying clothes, sharp knives, dining table mats) or pay attention to details (e.g., they could have put fresh flowers in the vase instead of keeping the dying ones that we found upon our arrival). If they don't, the full potential of this beautiful apartment will sadly remain wasted.
