Iris's apartament is stunning!! We loved it and it was super clean and orderly. It's right next to the train station Atocha, which allows you to reach the airport and any other zone of the city in little time, and you can reach sites such as Museo Reina Sofia, Museo del Prado and Parque del Retiro by foot. Iris was not there but her friend Florian helped us and they were always kind and helpful. I would totally recommend this apartament to anyone who wants to visit Madrid, given that if I had to go back to the city, I'd definitely choose Iris's apartament again. Hope you'll enjoy it!!
