Paulo is WONDERFUL!
The apartment itself is exactly as it looks in the photos - filled with light all day. It's actually like 2 seconds off of Rossio Square, which is the main plaza of downtown Lisboa. We could reach just about everything we wanted to do on foot within 20 min, and things that weren't walkable were easily accessible by metro or train.
Mostly importantly, Paulo was every bit the "superhost" he's been designated. He met us on time, showed us our amenities, and took 20 min to give us all kinds of recommendations over a map of Lisboa that he gave us. He repeatedly emphasized that we shouldn't hesitate to contact him should we have any kind of question. He even sent a message to check on us the second day of our visit. And sure enough, when we did have questions, he was incredibly fast with the reply.
We can't say enough lovely things about Paulo and this studio. We'll definitely be back whenever we're lucky enough to be in Lisboa again!
