We had a great stay in Nelson's studio. It was very conveniently located and had just what we needed :) Although small, the studio easily accomodates 2 people with a suprisingly comfortable pull-down bed. All you need to cook and even a washing machine.
If you are looking to be in the heart of "La Chueca", are on a budget but want something convenient and comfortable, we recommend Nelson's studio.
