The flat was perfect for what we needed. it was only a 20 minute walk to downtown or a cheap bus or metro ride there. the bus stop is right outside the flat and the metro is only a 5 minute walk.
the flat was clean, the bed was very comfortable. the view was amazing, we had breakfast on the balcony multiple times. the kitchen was well stocked and the host was always available to address any concerns. I absolutely recommend renting this flat when you're in Porto.
