We can't recommend Julia's flat enough. It is placed at the heart of the city and all the main sights of the city in the Old Town are in walking distance, as are the central market, bars, restaurants, etc. - everything can easily be reached.
A bakery is just next to the building for a fresh breakfast in the morning :) A bus stop can be found in the same street. Although, bus stops to the beach or the City of Arts and Sciences are within 10 minutes of walking distance.
The flat itself was very clean, cosy and the air-conditioning is just a blessing in itself :) Enjoyed our stay there very much!
