Paco's place is on the northern part of old town, we had a great luck to be there. It felt like we were at home.
Paco is a great guy, he welcomed us and gave us some local tips.
Free street parking was a challenge, but we managed to find it, alternatively there are parking garages nearby. Also the street was a little noisy in the morning, but we wanted to be in the centre of Seville so we couldn't expect peace and quiet :)
And off course, grocery stores, tapas bars, restaurants are all around..
