This apartment is just a block off of Calle Mayor and Plaza Puerta del Sol which is a major Metro stop. The apartment was very clean and light. The air conditioning worked very well and the kitchen had dishes, etc for 4. It has a dishwasher, stove and cooktop, microwave along with a clothes washer. There is no dryer but there is a clothes drying rack and ironing board with iron. Angel provided some soap packets for the clothes washer and the dishwasher. The master bath has a tub/shower combination and the second bath has your typical European shower. Hair dryers are also provided and Angel includes wash cloths in the bathroom (unusual for Europe).
It was very easy to get to the Metro stop and cabs are also easy to flag down at the Plaza. There were plenty of places to eat within walking distance and Angel provided a list of places that he recommends. Some of the restaurants are very popular and you need reservations such as the Casa Botin and Casa de Valencia. We couldn't get reservations at Botin but did at Valencia. We had the paella and really liked it.
The closest supermarket is at El Corte Ingles which is a large department store with the grocery store in the basement.
The large wooden shutters definitely keep out the light but there was some street noise (you're in the middle of a major city) so if that bothers you, bring some ear plugs. Angel was an excellent host. He met us outside at the apartment and gave us a tour of it. He left us a welcome bottle of wine. During our stay, Angel texted me just to ask if everything was going well, which it was.
We would definitely stay here again. The apartment was roomy and centrally located, public transportation was close and Angel was a great host.
