We definitely recommend this place for your stay in Madrid. We stayed here for 5 days for Mad Cool festival and we have nothing but kind words for MJ and his place. First of all, the location is perfect, in 200 meters around you have 24h Carre four, McDonald's, Burger King, fruit market and other stores that you need. Metro is around 3 minutes walk from the apartment and it can get you downtown very quickly. Also, there is a night bus N10 which is convenient if you're up for nightlife.
Second, the apartment is very and suitable for two people. It has all the things you need and although it is not spacious, everything is arranged in a fantastic way. You even get a bottle of wine as a welcome gift 😊 All in all, great value for money.
And thirdly, MJ is an amazing host. Very friendly, available all the time on WhatsApp and you can contact him for everything. Self check-in is very easy because he'll call you and guide you through everything very thoroughly.
Hope to come back again and visit his place again 😊
