My friend and I stayed for 5 nights in this lovely apartment. We met Bruno at our arrival: he made us feel very welcomed and we appreciated the little Port bottle sample on the kitchen table. The apartment is clean and very bright and I would definitely come back or recommend it to any of my friends coming to Porto. Our only regrets: the kitchen sink is very small (but it's not really something that you can change) and the bedroom has a spring mattress, which is just a tiny bit annoying noise-wise but comfortable anyway! Maybe something that can be added: a light bulb over the shower (the cables are there but there's no bulb for some reason)? Other than that, the apartment is located next to a very few nice bars and a little commercial street but we found that the area was quiet nevertheless. You'll reach some highlights of the historical center within a 10-15min walk. We actually did most of the sightseeing by foot!
