Everything was perfect with Alvaro's place, and unbelievable how centrally located. Just a stone's throw away from Plaza Mayor and all the touristic sites. Beds were comfortable, it was nice to have the two bathrooms and the kitchen was very modern and well-equipped. There was a percolator for a coffee maker, we wished there was a more modern form of coffee maker but we went out for coffee anyway. Instructions were clear on how to self-check in and we appreciated the privacy. I would stay again next time I am in Madrid.
