Porto has a lot of buildings that are abandoned or undergoing reconstruction. Joao and Miguel did a fantastic work renovating their place. Our apartment was very nice, bright, super clean and with modern & design furniture. It feels really cosy and was the perfect place to recharge after hours walking up and down the city. It was also very quiet, so you'll sleep well.
3mn from the apartment, you're in Bolhao market and have all shops in surrounding streets. Lots of restaurants nearby, supermarket too for those who prefer self-catering options (kitchen fully equipped, there's even a dishwasher).
We certainly recommend it, Joao and Miguel are easy to communicate with and very helpful. We'll come back.
