Great location, cozy studio flat with breakfast and everything you need for a comfortable stay in Madrid. We stayed for three nights and Paula was very welcoming although we arrived after mid night. She gave us instructions on where to get SIM card on Sunday which was super helpful. They run a shop nearby and are very quick in response which makes things easy in case of an emergency. All the main tourist spots are in walking distance as well as Atocha station if you are taking the train, Renfe, to other parts of Spain. Totally recommended for a couple.
