João's place is perfect for a single person or couple wanting to explore Lisboa's beautiful center. It's equipped with everything you need for a pleasant stay, including a washing machine that came in pretty handy.
The Castelo de São Jorge area is beautiful, convenient to public transit, close to sightseeing spots, and quiet at night. It felt great to stay "inside the castle".
It is true that the shower is pretty small, even for European standards.
Words of advice: Look for Elevador Castelo + Elevador Pingo Doce ;)
