We had three great nights in Lisbon and the lovely apartment contributed its share to the beautiful experience. It's an old house, but the apartment has been renovated and is cozy, with modern ikea style furnishing and perfectly clean. It is also perfectly located in Barrio Alto (we discovered the whole city by walking) and there is a lovely coffee house (Copenhagen Coffee Lab) just around the corner for breakfast as well as a small supermarket for groceries.
All in all - perfect spot to explore Lisbon!
