The location of the apartment is great, it’s within walking distance of a lot of the main attractions in Porto and of nice food places (Zenith, Garden, Nicolau (the best), Nola etc).
The apartment itself is as described, the only downsides were that it was quite cold (we visited during March) and noisy (the Metro outside), but nothing unbearable. The host had great communication and check-in/out was easy.
Based on location alone I’d recommend this apartment!
