Tania's place is in a great location and was very affordable. I stayed for the month of July on a work trip and found the place catered well to everything I needed. It's not exactly luxurious, but for the price I think it was very good. It did get a bit noisy in the early mornings as it is right behind a pastry shop, so bring your earplugs if you are a light sleeper. Wasn't a problem for me as I was up for work in any case. Air con and WiFi were both great and bed very comfy. Super clean place and everything was provided for really well. Tania was super nice and very helpful with recommendations for literally everything in Madrid.
