Ana is a wonderful host. Her flat is welcoming and comfortable and surprisingly quiet. It is very close to Casa da Musica and the wonderful Museo de Serralves. Ana herself is an interesting and knowledgable woman who does everything she can to make your stay enjoyable and straightforward. Breakfast is fantastic. Ana leaves it for you so you can help yourself when it suits you. I can't recommend Ana's home enough. It suited me to be a little way out of the centre of Porto and it is so easy to get to both the sea and the centre.
