We had a brilliant stay at Ana's place. The apartment was clean and although small it had everything we needed, even a hairdryer and a coffee maker. The bed was comfy and the shower was great.
The main street around the corner is brilliant, the street is lined with bars and the atmosphere is great (but with double glazing it isn't noisy in the apartment). Some of the nicest and cheapest bars in Madrid right on your doorstep.
It's a short walk to all of central Madrid and right next to the metro stop in case you want to go further afield. We would definitely stay here again. Thanks Ana!
