Isabel’s place is awesome, looks exactly the same as the pictures. Perfect location - right opposite to the San Bento station (the famous station with beautiful tiles). Everywhere is walkable (churches, Liveria Lello book shop, the bridge, Taylor’s Port - a wine cellars etc). Didn’t take any public transport at all.
Isabel responded very fast, she gave us loads of local tips and recommendations, but we only stayed for a day so didn’t really have time to visit all of them. She is very thoughtful and helpful - she made sure we are okay to get in and didn’t get lost (we checked in late at 11pm), instructions to self check-in is very clear and easy to follow.
There are 2 large door windows and small balcony outside each window. There could be a bit of noise if you open the windows as it’s in city centre but we slept without windows opened so it’s not a problem for us at all.
Overall highly recommended and will definitely come back! P.S. Porto is one of the most beautiful cities I’ve ever been!
