This flat is very great: as the pictures, really clean, close to city center and close to restaurants and bars. Chueca barrio is the gay quarter: lots of people at night, really safe, great if you want to know the nightlife in Madrid and visit the day.
Sarai did welcome us and explain how to get in the flat, showed us things around...really nice person.
Around the flat you have San Anton market with supermarket Supercor, bakeries and nice restaurants (we went in Arabia and Palosanto). If one day, I visit again Madrid, sure it will be with Sarai and in this quarter!!
