Great host: friendly, accommodating and helpful even though our check-in time ended up changing on the day due to our travel arrangements falling through at the last moment.
The apartment was great: a central location close to the Plaza de España metro station and within walking distance of the Gran Via. Also numerous restaurants and a grocery shop nearby. Quite spacious and contains all the basic things you might need on an extended stay (dishwasher, washing machine, blowdryer, kettle, etc). The main negative is that the bathroom is a bit old, if you don't mind that then there's no problem here. Didn't get much chance to check out the terrace since it was a cold February.
