Lisbon is inexpensive. Example: Italian restaurant similar to Bella Italia. One garlic pizza starter, 1 very large pizza with many toppings, 1 lasagne, 4 drinks and 2 deserts came to around £20.
The city is more interesting than pretty. There is a lot of graffiti/street art. Many buildings need work done, but there are some unusual structures, winding and hilly paths, fountains and cafes.
There are some amazing city views. The view from Lisbon castle is one of the best city views I have ever seen. There are also many other city views to choose from.
The famous old yellow trams are not everywhere. Although this is the main symbol of Lisbon, they are mainly designated in the old Alfama district.
Knowing which type of transport tickets to buy can be confusing. It is worth researching this before you arrive if you plan to use the trains, buses and trams a lot.
The day trip to Sintra is an absolute must. This was my favourite part of the whole trip. The picturesque town 40 minutes out from Lisbon is like, in some areas, being in an adult Disneyland.
The suspension bridge in Belem is a stunning sight. Although I saw this, almost copy of the Golden Gate Bridge in photos before going to Lisbon, the surreal noise that sounds like something out of Harry Potter, makes this one of the best attractions.
Overall, I really recommend people who are interested in cities to have a 3-5 day trip in Lisbon. It is not somewhere I would particularly go back to, but that’s just because there wouldn’t be enough to see that I haven’t already the first time. Overall 4 stars!
