My girlfriend and I stayed at Monica's flat for 5 weeks and I have to say it was everything we wished for and more. Very well equipped, close to shops and restaurants and spitting distance from Plaza De Espana. There is a Lidl just up the road if you want to do more of a bigger shop and just outside the front door there is a small bakery and fruit & veg shop which kept us going.
The location is brilliant, the flat is close to two metro lines which connect you to the rest of the city although we found ourselves walking most of the time unless there was somewhere further afield.
Monica is a gem. We needed to get a hold of her once or twice during our stay and she was very quick to sort us out and was even happy to give us a few recommendations during our stay. The listing didn't advertise but the sofa can convert to a double bed in a pinch.
Can't thank you enough, Monica. All the best.
