Lisbon
Lisbon is a big city to tackle and unless you have four to five days, there are going to be some things you miss! I spent two days exploring all the neighborhoods of Lisbon (a lot of the time consumed by St. George's Castle which is a must see), one day at Sintra, and another day at Belem and Cascais. This was enough time for me to really enjoy Lisbon and the surrounding areas...and don't forget to experience Fado one evening with lots of yummy sangria!
