Porto is a stunning city, beautiful and easy to walk, people is friendly and you have a lot of nice buildings there's a lot to see besides the awesome coast area.
The appartment is cute and new, maybe a Little small but enough to two people, you have a balcony that heads to the Clérigo's Street it very close to the Tower of clérigos, and one block from the Lello bookstore, the Street is very moved and maybe a little noicy at night but it's ok. The bed is very confortable. The kitchen is full equiped with everything you need. It is also very close to the train station Sao Bento.
The only thing that we didn't like: the internet connection it's painfully slow, video calls are imposible and forget to watch YouTube.
I definetely recomend Claudia's place.
