Domingo and Carmen are excellent hosts who went out of their way to be helpful. Their apartment is a quirky and comfortable home from home in an excellent location in the centre of Madrid. Many local attractions are within easy walking distance. The apartment is also quite spacious. Our experience was almost entirely positive - our only suggestion for warmer months like July and August would be to have air conditioning installed. That would have made our stay 10/10 rather than 9/10.
