The apartment was charming and beautifully located. As described there were two bedrooms, two bathrooms, a living room, and fully equipped kitchen. One bedroom is large and bright, with a big window. The other is a good size, but only has a small window opening onto the building stairway - so little light and some noise from neighbors. The apartment is set up to sleep lots of people, with extra beds in each bedroom and in the living room - though that would be a bit cramped. Everything was very clean and nicely set up.
The apartment is up on a high floor, offering light and great views of Plaza Santa Ana. There is an elevator.
The location is really ideal. Plaza Santa Ana is filled with cafes, restaurants, and tapas bars. One of the best is across the street from the apartment building. There are small grocery stores down the street (but beware they open late 9-10am, and stay open late 10-11pm).
You are within easy walking distance of major sites, the big museums, the palace, the markets, and wonderful side streets for shopping and fun.
I would totally recommend this apartment and happily go back again.
