Mercedes is a lovely person and a delightful hostess, so I want to be able to give her apartment a fantastic review. The apartment is teeny tiny, newly remodeled, dark, and a good choice for someone who is not claustrophobic. Those descriptions may sound contradictory but a careful review reader who parses each word will be fully informed and better able to determine if this is the place for him/her. The apartment is actually a single room on the interior air shaft of a beautiful old Madrid apartment that Mercedes occupies. While visitors have a separate door and key, you do enter her apartment to get to your room. Once you have seen Mercedes' gorgeous sun and light-filled rooms on the other side of the entry hall, your room feels even more cell-like. One mandatory for me is wireless Internet access and that was a problem during my visit. Mercedes was apologetic and tried to help but her network remained a problem throughout my stay. In order to check the day's weather, without internet, you have to lean way into your air shaft window and try to see the sky---difficult. There is also an odd smell, like sewage mixed with curry, that bubbles up from the shower drain and permeates the space. The one window does not bring any light into the space but opening it did provide some relief from the smell, even if it also brought cold in. On the plus side, the remodel is new, the bed is comfortable, the kitchen is easy to use and stocked with Ikea basics, there is a generous wardrobe for clothes, and the towel warmer in the doll-like bathroom keeps the whole apartment warm and dries socks and delicates (and warms towels for shower--also provided). The bery best part about the apartment is Mercedes, her kindness, and her wonderful suggestions for seeing Madrid.
