Diana was a great host. The communication was perfect and quick. She recommended us places to visit and also warned us about some tourist traps around the city.
The flat was amazing. It was spacious and well decorated. It had amazing views of Porto city and Just 10 min walk to the Porto side. Diana also offered us 2 small bottles of port wine. I highly recommend this apartment.
The only problem with the flat was that it has a restaurant above it. So expect noise till late night. However, I did not have any issues with it. I'd rate the apartment 9/10.
