We had a lovely stay at Bom Retiro apartment and would fully recommend it to anyone. Carmen is a lovely, kind host, who was quick to reply to all our questions and was there waiting for us on our agreed arrival time. The apartment is perfectly to Heroismo metro station, which has a link direct to the airport and also can be used to help get into the city if you don't want to walk - otherwise the old town is around 15 minutes walk from the apartment which is very convenient. The apartment itself is in a very quiet street and it is exactly as shown in the pictures; perfect neat and tidy and beautifully clean. Carmen's apartment is perfect for a stay for two in Porto, which is also a very interesting city. When it was time for us to leave, Carmen had kindly made us aware that there would be no metro service at that early hour in the morning, so she kindly arranged a taxi for us, to take us to the airport; so the attention to detail was much appreciated. Obrigada Carmen!
