Antonio's place is just a one minute walk from the nearest metro station. To the train station at Sao Bento it's just a 15 minutes walk. So the location is just perfect to explore Porto and the surrounding areas. There are two supermarkets and a self service laundry five minutes away.
The room is in a townhouse and has all amenities like a good hotel room, including your own bathroom. The bed is very comfortable. Additionally, with six other rooms you share a very spacious kitchen (with everything you will need to prepare your food) and seating area, including a garden space. The entire house is very clean and well kept.
I have not met Antonio in person but he responded within one hour to all messages and was a very kind host. I am highly recommending staying at his place when in Porto.
