We stayed for 12 nights, which is easily long enough to separate the facts from the fiction and work out that the photos don't tell the whole story.
But here's the thing - the photos are entirely accurate, this is a lovely apartment, probably the nicest Airbnb that we have ever stayed in.
One thing that you might not work out from the photos is that there are THREE separate balconies, so if it's hot you can easily open the doors on either side and get a nice breeze. (Porto can usually supply a breeze!). So even though the temperatures were hitting the high 20s, we never needed to use the air conditioning.
It's a great place to work - the wifi is fantastic and the office upstairs is a really nice space. (Pro tip, there's a plug socket on the balcony in that room, so you can work outside in the shade).
Nuno & Anita gave us the impression that they really want to go the extra mile to make sure you have a great time. That includes a private wine cellar (with tasting notes), three pages of restaurant and bar recommendations, a one-day walking tour suggestion that would probably take you a week to do... everything was great.
Other things you might want to know - yes, the printer works, and it is really useful to print out all the forms and certificates you need to travel these days. The TV has Netflix, so you can carry on with the box set you were watching at home. But why would you do that, when there are some amazing restaurants within a 5 or 10 minute walk.
If the apartment is free, do yourself a favour and book it!
