We really enjoyed staying at Carlos's place.
The terrace/balcony is very large and relaxing. The apartment is very quiet and easy walking distance to two metro stations.
Carlos's hospitality was outstanding! He carried two of our bags as my partner had hurt his ankle.
We felt it was a great introduction to a less touristy part of Porto and would have stayed longer if we had more time. We stayed 5 nights.
Thanks Carlos for everything!
