If driving from Barcelona airport follow the signs for Girona/Francia AP7 on the Ronda de Dalt (B20). This is the expressway across the west of the city and can be quite busy at the rush hour. You will connect with the AP7 on the north of the city.
Alternatively, continue past the B20 exit and follow the Girona signs ( for heavy vehicles) on the A2, then the B23 which continues on as the AP2 and connects with the AP7 to France. Beware the A2 and AP2 have radar!
The AP7 itself, is the main motorway from France to Barcelona, but is never that busy. Continue up the AP7 until you reach Sortida 9 for Lloret de Mar, Blanes etc. Take this exit. Try and keep to the left at the peage, because you are needing to go straight in front and then head to your left (a road joins you from the right at this point, so be careful).
You are now on the C35 and should follow this road with signs showing Sant Feliu de Guixols/Palamos. Continue on this country road and you will pass the road for Lloret De Mar and then the turn off for Llagostera. Follow Platja d’Aro/Palamos signs. (Please note that the road number does change after Santa Christina d’Aro to the C31).
Continue on, passing Platja d’Aro and then Palamos. A sign will say Palafrugell 6 km. Continue on for 6km and take Exit 331 sign-posted Palafrugell sud, Mont-Ras and Platges. Continue straight ahead at the next two roundabouts and take a right at the third, following the Platges. After 300 yards, at the next roundabout, take the exit marked Platges, Calella, Tamariu and Llafranc. Continue for 200 yards through the next small roundabout, and then on for about 0.5 mile, over a few “bumps”, to the next large roundabout. Approach this junction from the inside lane (right) because you need to take the very first exit, marked Sta Margarida /Ermedas. This small road is the Old Calella Road and Casa Dos Torres is situated on it. You will immediately pass La Guitarra on the right hand side. A mile further on is Costa Este, again on the right hand side. Continue on for about one more mile and you will be in Calella. When you enter Calella, there is a small piece of land on the right hand side with a few trees. Casa Dos Torres is the second house on the right after this. The house name is clearly visible. There are green sliding gates, a few pine trees and a house with two towers!
