Lovely stay in a pretty and convenient but quiet apartment. Carlos was very responsive when our key did not work, coming with a can of WD-40 and a new key himself, and gave very helpful recommendations of things to do during our time in Porto. When the driver he had arranged for us to take us to the airport tested positive for Covid, he came himself at 4am to drive us to the airport. The bed was comfortable and the neighborhood was a residential area that was a beautiful walk into the city center, or very nearby to several subway lines if you prefer. Highly recommend staying here!
