The location was very good as there are almost all important sights and restaurant/bar areas as well as El Retiro very close by. The price is fair for the size of room that you get. The room, kitchen, bathrooms and apartment in general are clean.
On the contrary the check-in lady is extremely unfriendly and does not care much. And by far the absolut worst: the windows do not close correctly and they are super old and thin and therefore it is crazy loud. The whole Friday night from 6pm till 9:30am on Saturday there were drunk people on the streets screaming and making noise. Even with noise cancelling ear protection it was impossible to sleep.
One of my worst nights in long time and even though I prepared myself with bringing ear protection with me. During the week it might be a bit better.
The owner should invest in some windows and then the experience would be great in total.
