Rosa is a very nice host, I trained my Spanish :) The location is int the centre of Madrid, between narrow streets. It is a very quiet location, no noises from neighbourhood shops and bars. A lot of bars and coffee bars in Madrid. It is in walking distance to most of Madrid places to visit. In fact, this center is smaller than you would think of it just by looking at google maps. Metro stations are in locatied close to themselves. So, travelling by metro is not the fastest way to get somewhere.
