The apartment was well equipped and the host gave us a lot of useful information for our stay in Porto. Unfortunately we had to check out 2 days in advance because we could not get any sleep. The mattress was extremely uncomfortable, felt like we where sleeping on the floor. We asked for alternative arrangements but could not come to an agreement. Host refunded us 'some' of the money for the 2 remaining nights and we had to find alternative accommodation on short notice.
