Lisbon has been on my travel bucket list for a very long time. This summer I decided it was about time to visit Lisbon, the second oldest capital city in the world (after Athens). Lisbon is built on seven hills, with the São Jorge hill being the highest of the city. Located on the summit of this hill is the São Jorge Castle, overlooking the city with some breathtaking views. On top of this highest hill, and right next to the castle you’ll find (if you search well) Solar Do Castelo, so be prepared for a climb whenever you go to the hotel! In this blog you can read about my stay, a complete hotel review.

The capital and largest city of Portugal is a beautiful charming city with several characteristic Bairros (neighborhoods) de Lisboa with many historical culture and unique architectural landmarks. It's one of the oldest cities in Western Europe and in the world.

Lisbon is situated at the mouth of the Tagus River and is Europe's only capital city along the Atlantic coast. English is widely spoken so language barriers shouldn't be an issue if you travel to Lisbon.
