Great flat, right in the old center of Porto. 5mn from main Train station. 10-15mn from Luiz Ier bridge (with all bars, restaurants, and Porto caves across). There a free and safe parking spot if you travel by car. The apartment is very nice for 4 people, with all accommodation (bed sheets, towel, coffee maker). Super clean and cosy. The italian shower is just amazing.
Also, Daniel is super nice. Warm welcoming, bottle of Porto, coffee, pack of water offered. And the best is all nice tips for restaurants, bars and place to visit for our vacation inp Porto and Portugal. I would definitly recommend this adress.
