We had a great 4-night stay at Conseulo's apartment in the center of Madrid. You just can't beat this location. It was a 10-minute walk or so from the Sol metro station and then only a block into Plaza Mayor. It's the perfect base for exploring the city. They were very accommodating, waiting until midnight to let us in as there were some disruptions with the metro due to construction. We had cheese and wine waiting for us and got a nice tour of the flat. It's such a lovely home with great decorations. We used the kitchen to make coffee and a small breakfast, did laundry, and managed to work a bit from here. Don't hesitate to book this great place with super friendly hosts for your trip to Madrid! Oh and be sure to book a table at Botin (oldest restaurant in the world), which is right around the corner.
