This is a really beautiful, stylish apartment and Luis is a great host - his interactive map of Porto has literally everything on it! The little balcony overlooks a quiet garden and it's a great spot for a glass of wine or two (theres a great old fashioned shop over the road for supplies too).
The neighbourhood is great, lots of bars, shops and restaurants and it's walking distance to the historic centre. Be aware it's quite a climb back up from the riverside but it is worth it!
overall a lovely place to stay with a great host.
