I ́m a real estate broker at iRent Madrid, not the owner of the listed units. All bookings have a one month ́s admin fee (might be lower if less than 3 months rental).
I manage a large number of rooms and private apartments, so feel free to contact me for other options, specially if you are looking for few rooms in the same apartment or an apartment for several people.
I try to provide as much information as possible on the listing so that you don’t miss any detail. However, if you need more information, do not hesitate on asking me. I'll be happy to help you to find your new home!
