The apartment is very well and centrally located in a lively and beautiful neighborhood of Madrid. Therefore, the city center can be explored completely on foot within half an hour without any problems.
The size is rather poor - however, this is not a problem if you use the apartment primarily for sleeping and as a starting point for exploration. The room was clean and equipped with microwave plus various other utensils. The bathroom also left nothing to be desired, apart from the fact that it is not an extra room, but the toilet and shower in the room are only separated by a partition.
Luis as host was very interested in making the stay as pleasant as possible. Communication was almost immediate and without any problems. Should I find myself in Madrid again, I will think about coming back :)
