Conidia was a great host. The apartment was very clean and spacious. The only small issue is that the door is straight onto the street so it can be quite noisy and light does shine in (we arrived during the Real Madrid game so it was loud one night but okay the rest of our stay). It's well connected to the metro- 15 minutes walk from Delicias metro and 20 mins to the train station. Overall really lovely stay in Madrid.
