The location is conveniently close to the metro and Buen Retiro Park, but the apartment gets dusty quickly since it overlooks Madrid's major railway station. The apartment has a nice layout, with doors that separate the living area and kitchen from the bedrooms. The kitchen needs a little bit of updating-the oven door doesn't seal properly, causing the outer handle and door to become dangerously hot when the oven is on, and some of the kitchen utensils and knives are old and difficult to use. But overall the apartment is spacious enough for a family and the beds are quite comfortable. Although Felix wasn't able to be there to meet us, he checked in a few times with a message to ask how things were going. The concierge of the building and the neighbors are friendly and the apartment complex has a nice open area in the center. It's also close to many restaurants and supermarkets.
