My family stayed at Pedro's place for 4 days on our way back from exploring northern Portugal and Spain and it was the perfect apartment to take in Lisbon one last time. Loved the location - felt more authentic than other neighborhoods we had stayed in. Apartment is charming with high ceilings, moldings - you feel like it's from a French movie!
Pedro lives in the building with his family and is very nice, respectful and responsive. It was a hot weekend when we stayed (99F+!). But the building is naturally cool. Plus, Pedro provided great fans, and that was enough to make it more than comfortable. My baby had no trouble at all.
Someone also said there was no shower curtain but we didn't find this to be a problem. The way the shower is built there's a wall to protect from water going out so it's really no issue at all.
Would definitely stay here again!
