I stayed at Catarina 's place for four nights after finishing a long bike-tour from Bilbao to Porto. Catarina is very communicative and service-minded! She gave me suggestions of where to eat and what to do in Porto, both in person and in her cool city-guide that you could download to your Phone and use in Google maps. Porto city center is just a 20 min walk away and the metro is conventently located across the street. The appartment is very clean, with three bedrooms, a nice terrace where I could safely keep my bike, one shared bathroom, a fully equipped kitchen and an extra toilet. The room was spacious with a comfortable bed. The small downside is that the appartment tends to be a bit noisy, especially if you have the room close to the bathroom and when other guests come and go frequently during the night. But that is just a part of the experience when travelling!
