We are going to Barcelona next month and would like to hire a private driver for 4 people to go on a day trip. Recommendations? Thanks!
We used Barcelona Day Tours http://www.barcelonadaytours.com/
They were great, on time, professional, etc. and we were very happy with them. They get great reviews on Trip Advisor which is where I found them.
I bet you must have already come back but I though the info could be useful for someone.
Unless one plans to see everything at once, Barcelona is not a big city and is perfect for walking to all the main sightseeing points with a guide if one is a good walker (eg, Casa Batllo, La Pedrera, Sagrada Familia). If possible do not join too many points on the same very day, might be too much!
