The perfect location if you want to be close to Atocha train station. Mattia was great with responding and while we did not meet him in person, the women who met us for check in was very nice. We only stayed for one night but the apartment had everything we needed. The beds were very comfortable and the apartment was clean. There was air conditioning but it is only located in the living room (none in the bedrooms) so if it was really hot out it may have been uncomfortable but we were okay during our stay - the main bedroom is located right off of the living room so you could probably just leave the door open to get the AC. If you are looking for a good place to stay close to the train station this apartment is perfect.
