We've been hosted in the so called "senior suite" at Cibeles Boutique.
Unfortunately our stay was quite unpleasant for the following reason:
1) Pictures and floor plan shown in the listing were different from the real "suite". All the windows overlooked two small inner courtyards with very little light. One of the inner courtyard was full of some sort of big ventilation pipes which produced a loud noise distinctly audible from the bedroom from 6.30am to 1.30am;
2) Due to noise, we asked to change suite, but it was possible only for the last night (out of three);
3) The suite was supposed to have two bedrooms, but one of them was basically inside the kitchen/living room (which are the same room) and it had no door.
