We got our luggage, a taxi and drove to the Hilton diagonal. The cost was $35 euros and he took a credit card. We checked in and were very pleased with our room; we showered, and took the city bus tour. The cost was 25 euros each. We only took the blue line which took us past the la sagrada familia. The tour lasted two hours. We were amazed at the history of the city and the influence of Gaudi everywhere and all the SCOOTERS!!! We did not feel like taking the red and green line tours. It would have required 4 more hours and we were just exhausted. We had dinner at the vibe outside and retired to our room for the night. We got some much needed sleep.
