We stayed here for six weeks from June to August and had a great time. We were working remotely for the duration of our stay so we can verify that the internet/Wi-Fi is really fast and really good for working remotely.
Location-wise, there’s just so much on your doorstep. In particular, lots of good food and coffee.
The only negative we can think of is that when it is warm, the sleeping area in the loft gets very warm! But thankfully there’s a good fan with a nighttime mode that helps a lot with that.
Would thoroughly recommend staying at this apartment if you want to explore Porto!
