Fantastic apartment and the location was excellent. The fact there was air conditioning in all 3 bedrooms AND the lounge/kitchen/diner was a real selling point as it gets so hot in Madrid in summer that you really do need it. The metro was 5 minutes walk (if that) but we walked to Puerta del Sol, Plaza de Santa Ana, Plaza Major, and The Royal Palace very easily from apartment. There is a Carrefour just up the road (again 5 minutes) which provided us with all the essentials for breakfast etc and there is a nice TGI Fridays on Grand Via which you can see from the balcony. We also ate at a Vegan restaurant called Vega (need to book in advance if weekend as very popular) which was very good and the restaurants in Plaza de Santa Anna were also enjoyable. Madrid is a busy noisy city and the apartment is right in the heart of it all, it is comfortable and done to a high standard and Alfonzo was very helpful and let us stay till 2pm, even though check out was 12pm, as our flight wasn't till 5.30pm - would definitely recommend.
