It was fantastic to spend my time in Porto in Carlos' flat. It was really clean and perfect to be in. Close to everything just a small walk distance. It was perfect and I could imagine myself living there :). Carlos was a really good host. He received me with a big smile and it was really nice showing the flat around. Flexible check in and out hours, which is a big plus. Furthermore, outside were a lot of taxis in case of need. This flat made my Porto experience to be amazing.
