Would definitely stay here again as the location, communication and check-in were all fantastic. You can't beat the Praca Riberia square and waterfront location, and the hosts are very accessible and helpful prior to checking in. I really appreciated that they met us in the square at check-in, as I'm sure we wouldn't have found the building without their help! Given the building's history and location, you can expect a few ants -- so just keep your bags off the floor and keep food (we accidentally left a sealed CLIF bar in our bag) in the kitchen or lounge area. Thanks for a nice stay in Porto, already looking forward to returning!
