Long stay. I've been doing the AIrBNB for two years now, and it's not often I've experienced communal living, but my stay at Manual's flat worked out well.
Very clean. Excellent bed & shower. Kitchen use was easy enough to enjoy any type of prepared meal.
The flat location is very near a few huge parks for enjoyment on nice days; also, easy access to the Laguna Station.. Madrid's fantastic metro system to anywhere within the city.
