This place is amazing!!! First of all, staying in the Alfama district is an experience one must have. It's magical and you seem to be in a fairy tale medieval town (or just pre-1755, at least). Artur met us at the Fado Museum to help us locate the apartment and then helpfully explained so much about the area via maps.
And THIS APARTMENT! It was a welcome respite amongst our busy days. The place is modern and spacious with everything we needed. The shower is large and lots of warm water.
There are 2 huge door/windows that could be kept open all the time. We visited in mid-June. Lisbon is a lot like my experiences with coastal southern California - pretty much 70-ish the whole time with no bugs worth mentioning. It was so perfect.
Highly highly highly recommended.
