Mario's place was an ideal base to explore Porto. You're right at the junction between the Main station, metro, shopping area and the famous Dom Luís I Bridge. It doesn't get more central than this. Yet, it is surprisingly quiet, as the apartment faces an inner the courtyard. It actually in the same block as the Intercontinental. The underfloor heating in the apartment is also fantastic. This is rare in Porto as it does get quite cold in winter and most apartment are not so well equiped. The apartment is self is also very modern with a well equiped kitchen. This would be the cleanest apartment I have ever stayed. Everything seemed almost brand new! Mario and Helena were also very accomodating with my late check-in. They even gave me a small tour of Porto during the pickup. I would recommend this service, especially if you are carrying around luggages and wanted a hassle free arrival. I highly recommend Mario's place if you wanted to be somewhere central, modern with host that you can rely on. Thanks Mario and Helena!
