The apartment is as described. Eduardo even organized a taxi for us at a pre-arranged fee that made it very convenient to get to the apartment in the evening when our plane arrived in Madrid.
On arrival, Eduardo waited for us and explained all the important information.
The location of the apartment is excellent. Very quiet apartment in the city centre. We could walk to all major places, museums, etc., and we didn't have to use public transport there during our stay.
There are many cafés nearby where we could have breakfast and a shop where things could be bought.
