My time at Rosario's place was just awesome. I stayed there for one month and I always felt very welcome. The place is very clean and you feel ultimately at home. There is even a fridge in the room and Rosario provided me with so many sweets, coffee and other delicious things. The area great as well, stockwell Station is very near by and provides you with northern and victoria line.
I can absolutely recommend this place, since it was just amazing!
