My boyfriend and I stayed here during our 4 day trip to Madrid and it was a perfect little studio for the two of us. It was clean and comfortable and in an amazing location. We flew in to Barajas airport, and it was very quick and easy to take the Metro to the flat and the apartment was only a few blocks from the nearest station. However we only ended up using the Metro to get to and from the airport because everything we wanted to see in Madrid was within walking distance from the apartment. It's right in the middle of a very lively shopping area with lots of bars and restaurants but since the apartment is in the interior of the building it is very quiet and you get none of the street noise. Perfect for someone who likes to be in the heart of the city but also wants to be able to get a good nights sleep! Julio was very helpful, making himself available through email and by phone and sent extremely detailed instructions on getting to the apartment and finding it once inside the building. He was also very accommodating to our schedule since we arrived in Madrid quite late and didn't fly out until late. We were able to arrange things with him as far as key drop off and pick up and luggage storage so that everything was quite convenient. Julio was also available to make recommendations for things to see in the city and there were many guidebooks and maps in the apartment available for use. This was my first time using Airbnb and I found the experience much more enjoyable and economic than staying in some generic characterless hotel and highly recommend it!
