Nelson's apartment was very central in the lively Lavapies neighbourhood - many great restaurants and bars. For the price it was a good place to stay in Madrid. However, the apartment does not have wifi which is advertised and this was a real let down as it made planning our visit difficult. Furthermore, there was a lack of hot water in the shower. Overall, if you want a cheap and clean place to stay near the centre of the city this apartment would likely work for you.
