We had a great stay in Ricardo's apartment. We had a late flight which was also delayed. Despite the late arrival, Ricardo warmly welcomed us and told us extensively about Porto. He was always available should we have had any questions during our stay.
The apartment is brand new and very well finished. The high ceilings are also very nicely decorated. The furniture is of high quality. The bedroom has plenty of cupboard space and an iron and ironing board are provided. The nice bathroom has a shower with a firm water pressure, which is very nice. The location of the apartment could not be better: in the middle of the car-free shopping street. Everything is within walking distance: shops, restaurants, railway station, Ribeira neighbourhood and Douro river. The metro is just around the corner which we took back to the airport. There is a direct line to the airport which took less than 30 minutes and cost us only € 2,20 per person. What might be a downside during hot days is that there is no air conditioning. But during our stay we did not really miss it, even though there were days of over 30 degrees Celsius. Just open the balcony doors and you have fresh air inside.
All in all we highly recommend Ricardo's apartment should you visit Porto :)!
