Joao was an awesome host! The place is great - exactly like the photos, the bed is really comfortable and the location is perfect for walking along Rua de Santa Caterina and only a 15 min walk from Trindade train station (up hills, but very doable with big back packs - we were travelling for 5 weeks), which is a quick ride from the airport (I think from memory around 30 minutes, give or take). There is a closer metro stop to the place as well, but if you don't want to change lines it's easy to find. When we arrived Joao took us through a big map of Porto and pointed out his favourite local restaurants and how close the best tourist sites are, and explained them with so much passion and detail, it's clear he loves his city and loves meeting new people. The place has big windows which is great for the heat, and has a great main lounge area to chill out after a day of exploring. Joao left us 2 Pastel de nata (Portuguese tarts) as well! We felt very safe in the area and had a great stay.
