Absolutely ideal place for 1-2 people to stay when visiting Porto. You're a block away from the main square and a five minute walk away from a plethora of restaurants, bars, etc. You're also about a 10 minute walk from the area where a lot of walking tours meet. I couldn't recommend this apartment more for solo or duo travelers!
It's not incredibly ideal if you're renting a car, but I was able to park mine in the garage right down the street and paid a total of 40 euros to do so for two days.
Oh, and the bed is super comfy!
