Lisbon is a vibrant beautiful and friendly city. Food and entertainment is brilliant. However, you should be prepared for some steep hills but there are many trams if the climb doesn't appeal and taxis must be among the cheapest in Europe. The food markets are worth the visit alone with the restaurant stalls and live entertainment. Time Out market and my favourite Campo do Ourique market are must visit venues. Rooftop bars are a feature and I particularly reccomment the «Park Bar»
