The location can't be any better... Is near a lot of the attractions in Madrid.. where one can go out... and return for a rest and go out again. Close to everything including the Metro.. or walk down Grand Via at night for night photography.
Is close to El Corte Inglés too which has very nice supermarket for getting food to cook at the apartment. The kitchen is adequate for cooking.. Could use few ready items though: oil, salt, sugar etc.
The place is unique .. think of an apartment found in Architecture magazines.. it make good use of space.. and has a theme of living in the forest. Good visual designs not necessary interprets to functional design though lol... Is good experimental lab of not what NOT to do for one's own apartment too lol.
Anyways, highly recommend those travelling to Madrid to stay at this place
