We loved staying at your property, the location was better than anticipated. It was an easy walk to Porto and Vila Nova de Gaia has plenty of shops and restaurants, we even joined the local gym for a month.
As we stayed for a month it would have been good to have extra towels and bedding, also a second set of keys as there was two adults in the unit. We also had no tea towels or a kitchen sink plug. Just a note, Tourist Tax is 2€/adult for a maximum of 7 days.
