My wife and I had a great time to stay at Maria’s apartment for one week, which is conveniently located close to metro station Buenos Aires, bus stops and supermarkets. The WiFi connection is good and the heating system works well in winter. Maria and Carlos are very kind, very friendly and very supportive! Carlos was so kind to send us to Madrid Airport by his car for a small fee! We would highly recommend travelers to stay at Maria’s apartment when visiting Madrid.
