I lived in Barcelona for a few years but still go back at least once a year. I still discover new places and people everytime I go. With my wife and four close friends we have made Barca a yearly trip where we meet up in the same Hotel in the Gothic quarter and have the best few day's. My advice is to go during the winter months as you can still experience temps of between16 - 22. Hotel Rialto is excellent value and it's position in the gothic quarter 2 mins from La Rambla makes for a great starting point to explore.Top tip: when you walk the city always take time to look up as you will find architectual gems on every street. Amazing!!!
