Julian's flat is perfectly located to discover Madrid by foot. It was easy to check-in thanks to Julian's responsiveness and clear communication since day 1. The apartment was also sparkling clean when we arrived, and is perfect for 2 in terms of size (basically as you'd like it). It is also quiet and very well equipped!
The only thing was that we felt a bit misled by the ad, which mentioned and showed a photo of a washing machine. It was there indeed but with no detergent provided, it was actually impossible to use! We had selected the flat mainly for this reason vs. another one nearby, so it was a bit disappointing. No oil in the flat made it impossible to cook too, so I'd suggest to buy some for the future guests. These are liquids that can't really be found in 100ml packaging, and a hassle to transport, so it would have been very appreciated.
Apart from that we were very happy with our choice, thank you for everything Julian!
