Exchange Zones

We are a Spanish family with a 3 years old kid. We work as programmers -well, not the kid ;-) We live in a modern, sunny duplex with air conditioning and wifi. The flat is 5 min walking from the historic city center, but our street is very quiet. We are looking for 3-4 weeks in August preferably in London or another England city, because we want to improve our English. Girona has a very well conserved medieval city center. In summer, there is a lot of cultural activities, including free concerts in the charming jewish quarter. The nearest beach is about 40 minutes by bus, in Costa Brava (Mediterranean Sea). Barcelona is 40 min. by train. We live very near to the train&bus station (with buses to the Girona airport every 30 min.). Girona is also famous by his excellent restaurants.
