My wife and I stayed a total of 4 nights in Elmi's apartment (2 at the beginning of our multi-city trip and 2 at the end of the trip) and enjoyed our time there very much. Elmi was a great host- patiently waited for our arrival, easy to contact, low key and friendly. The apartment is about one minute from the Opera metro station and is very centrally located for walking to most of the sites one might want to visit in Madrid. There are quite a few restaurants and bars in the immediate area so it is a great place to wind down at the end of the day. The bed is very comfortable and the apartment has all the amenities needed for a very comfortable stay. (We cooked breakfast in several days and dinner as well one night.) The lift in the building is small but works great. We will definitely stay at Elmi's apartment again when we return to Madrid!
