Although we didn't meet João, lovely cleaner Sofia let us in and showed us the facilities and gave us a superb Recco for a great Pastel de Nata bakery just 1 minute from the door.
The apartment is well equipped and comfortable and right in the middle of the Porto action. Just 5 mins walk to Sao Bento metro for the airport. João was always quick to respond to my texts and very kindly booked us a taxi as we had an early flight.
If there's just one thing to say that needs improving... it's the bathroom and shower. You kind of climb 'up' and into the shower... it's pretty bizarre and there's absolutely no room to move freely. Bare this in mind if you have sort of mobility issues or indeed if a roomy shower is your thing. We kind of gave up which is fine for a weekend. The Sink too is super small, being just a tiny hand basin. Good to bear in mind. Other than that, great apartment!!
