Check-in went as agreed. We were met by a representative of Francisco. Central apartment, walking distance to most everything. Window/door (??) which was placed inside the original windows ensured that we didn't notice any of the noise from the street life outside!
The apartment was equipped exactly as described, but a small tip; some renewal of kitchen equipment. We ate all our meals out - holidays are like that for us - but for those who wanted to make their own lunch/dinner there would probably be a bit of frustration about the standard on knives etc.
Great bathroom, good beds. Everything contributed to our having a good week in Madrid.
Thanks to Francisco who gave us the opportunity to use the apartment!
