Pros: Location is great, the apartment easy to find. Close to Plaza España in which you find metros, trains, Aerobus stops for going to/from the airport, tourist bus stops, all the transports a tourist may need. A shopping mall nearby with a supermarket and lots of restaurants. The apartment has three bedrooms with comfortable beds. All windows are facing a main road, so there would be a bit noise from the cars at night, it didn't affect us though. We waited a few minutes for the host Anna to come, she was nice and show us around and how to use the facilities and appliances. Washing machine is functional, there is no heated dryer for the clothes but there is plenty of space for hanging dry them. It's a great idea that the host keeps the tourist guide books, brochures, maps and coupon booklets in the apartment, one may find something useful among them.
Contras: There are two bathrooms but only one of them has a toilet, I didn't notice until after I booked and read the user reviews. But anyway, it's not a deal breaker to me. The shower booth in the main bedroom is a bit too small, even for 1 person. Water temperature in showers fluctuated and sometimes difficult to use. But all showers in other apartments I stayed in Spain had this problem too, so I guess it's due to that type of water heater they commonly used in Spain.
