The stay we had at Juan Carlos and Nina's flat was fantastic. I arrived before the four others I was staying with. Juan Carlos was there at the flat waiting. The instructions on getting there were flawless and easy. Inside he gave me great instructions regarding the amenities inside the flat, and details about the best sites around. He recommended some great restaurants as well. But really, there whole city is full of great restaurants! The flat was spotlessly clean and very comfortable. Everything was perfect. Buying groceries and wine was easy (right at the ground floor) and there was a large shopping plaza within 5minutes walk. We were there to attend a meeting at the congress centre, which was an easy 10minute walk. Subway was 5 minute walk. Everything was easy simple access in a great area. Unquestionably I would stay here again when next in Barcelona! The hosts were truly excellent making for a very relaxing stay.
