My husband and I stayed with Sara for four nights and really enjoyed it. The check-in with Sara's husband was great and he gave us a lot of tips about what to do in Porto. Also, they gave us a bottle of wine as a welcome gift which was very nice. :)
The apartment is perfect for getting around in Porto. It's close to the major sightseeing spots but still in a quiet area. The shape of the apartment is also something we liked a lot.
