This was an amazing place to stay in Porto. Its just outside the centre but you can easily walk everywhere - we only used the metro to get to the airport. The flat is on a main road but the noise didn't bother us at all. our flight landed late at night and The Porto Concierge met us at the flat no problem and even took the time to give us some tips about the local area even though it was 1am. The flat had everything we needed and we loved staying there. I would highly recommend it!
