This is a comfortable apartment that's conveniently located for the Alameda de Hércules, with good coffee shops and restaurants within 10mins walking.
We visited in February and the apartment was pretty cold unless we had the heating on all the time – but the heating did the job and we were comfortable. My one complaint would be that there's very limited natural light in the apartment, although there are plenty of electric lights to make it bright enough to work. The kitchen has the basics you'd need to cook and the whole place was extremely clean. Bonus: loads of storage!
