Location, location, location! Alicia's apartment is just about as central as you can get. Restaurants, shopping streets and public transport (both metro and buses) are right on your door step. You can literally see all of them from the balcony.
The apartment itself is really spacious and airy, with lots of windows giving you a great view of Plaza Callao and Gran Via. Bed was comfy, kitchen had everything you would need and having a washing machine was very handy, so is having a second toilet.
Having a lift in the apartment building was a nice surprise as well.
Only downside is that there is a limited amount of hot water so if you have a long shower, it will run out and the next person will need to wait until the hot water system heats up again.
Highly recommend Alicia's apartment if you're looking for somewhere spacious, clean and in a great location.
