This apartment is superbly positioned for a stay in Porto. It takes literally minutes to walk to any of the key attractions and it is very easy to reach on public transport. The transfer from the airport via the Metro couldn't be simpler - a direct 25 min-ish journey and then a 5 min walk.
The apartment itself is exactly as the photos depict. It's super clean, and well equipped. The only thing missing is a balcony or area to sit out. Saying that, there are numerous bars, parks and cafes in the vicinity so it's easy to find a spot to sit out and read or have a drink.
The city is absolutely stunning and we easily filled a week by walking everywhere and seeing the various attractions. The views from the other side of the river are sensational and well worth negotiating the hills. We were glad of the lift when we got back to the apartment though!
We found a fantastic, friendly Vegan restaurant called Kind Kitchen, two minutes down the road from the apartment which we would highly recommend (even if you're not Vegan).
