The flat is very nice located near the city center. It is in a nice neighbourhood. From there you get very easily into the city center. You can also walk there :-) the Retiro is very close, too. And the train station as well. The room was small, but had everything you need. It also was very clean and tidy in all the flat. Cristian is a very nice and polite person. He even gave me many tipps for my journey to Colombia. It was really an honour to meet him, even it was just a very short time. All the best for you and hope to see you once again, Cristian! :-)
