We were very glad to stay in the apartment of Mario. It is in an interesting neighborhood of Lisboa, and absolutely central to getting around anywhere. It is not hard to find. The accommodation is as pictured and very clean and tidy. There is a comfy sofa for sitting, the bathroom and kitchen are spacious (both of which have a nice view), and the beds are excellent to sleep on. There are so many good recommendations about this place I can only suggest booking here as a number one choice. Mario may walk on water (according to what others have written) but he is a genuinely kind and helpful person.
