I trawled through page after page of listings before picking JR & Cloé's place, and it was totally worth it. It is perfect for exploring Lisbon: bang in the middle of the historical center, walking distance to everything, but surprisingly enough, absolutely quiet at night. It is a spacious 2-bedroom apartment, much larger than I expected, excellent for families with kids who need room to breathe.
There is a nice supermarket literally next door. Though the Baixa-Chiado metro station is a short walk away, for a group of 4, Uber is usually cheaper and more convenient.
This will be our top choice the next time we're in Lisbon.
