This is a lovely little flat close to the beautiful Retiro park and in what felt like a safe area. There are lots of supermarkets and restaurants nearby and it's quiet enough to get work done (which was how I had to spend half my stay). The metro stations are a decent 15 minute walk away but on very useful lines and the buses come even closer. Teresa is a great host. Very responsive to messages and helped me greatly when my bus from Badajoz arrived late into Madrid. The neighbours in the building are all very friendly and I'd recommend it to anyone wanting to stay in that area
