Ana ist the best host ever! We arrived somewhat late at night due to a delayed flight but it didn't seem to bother her at all. Ana prepared breakfast for us every morning before she left the house for work and when she found out that we were vegan she'd leave us fresh fruit and nuts. Aside from these aforementioned highlights, her apartment is great and the room we stayed in was ideal in pretty much every way. Also, it should be noted that Ana is a really really friendly and open person, I'm sure you can have the most interesting conversations with her if you happen to know a little Portuguese. We'll definitely try to stay with her again for our next trip to Porto.
