You can't get a more centralized location! We were able to walk everywhere we wanted to go during our stay. It is also just down the block from the Metro, which made traveling around the city even easier. The space was modern, clean and the bed was actually quite comfortable, which we have found is not always the case in Europe (by US standards). I also loved having an iron and ironing board!!! We didn't have any problems with the noise except for Friday and Saturday night, which is understandable. Marga kindly left earplugs on the bed stands and we were able to get some sleep. It is truly amazing, how late people in Spain are capable of staying up until! Overall, we would definitely recommend staying at Marga's apartment.
