Four friends and I stayed at Anabel's place for a 4 day trip to Madrid. The apartment is so central to everything in the city that we were able to walk to restaurants, galleries and everything in between really easily.
The apartment itself was fantastic - the beds were comfortable, kitchen fully kitted out (which allowed us to cook supper there one evening with no problems at all!) and sitting room big enough for us all to rest after a long day seeing the sights. There are three bedrooms - two with double beds, the third with a single and bunk beds. We would definitely return as a group of friends, and the apartment would also suit a family too. What surprised us the most about the apartment were the amazing views from all of the balconies over-looking the city - definitely worth being home around dusk to watch the sun set!
But perhaps the best thing about our stay was Anabel herself. She was so helpful in the run-up to our trip advising on travel between the airport and apartment, and even organised us a taxi to get us back. She also provided us with some breakfast items so we didn't have to go foraging on the first morning.
All in all we would highly recommend a stay. The apartment is ridiculously central and really comfortable - a home away from home!
