We spent 3 nights at Manuel's place while attending to a music festival near IFEMA. So in our case the location was perfect, a quiet area next to the activities we were doing.
Manuel's brother welcomed us to the check in, the communication with him was smooth and easy, he lives just in the apartment below.
There was everything we needed in the apartment and they even left some small foodstuff for breakfast or apperitives for us.
I just went to the city center once, it took about 10 mins walk to the metro station and about 25 mins from there.
Nice and clean home for who wants to stay in the outskirts of Madrid.
