This is a great location for seeing Seville and sampling the wine, food and atmosphere. It is 50m from a major square that is full of bars and restaurants, whilst the flat is quiet, the best bit is it's full of locals so the prices are very good.
The flat is very clean, has all the equipment you need for a stay, including for cooking if you want.
Its a 15min walk to the main centre and another 10 to the Cathedral, at a leisurely pace, there are lots of buses near by and we found getting a taxi easy.
Highly recommend.
