This apartment isn't big but it's exactly what you want if you want to visit Lisbon! Definitely enough space for couple and the location is AMAZING for exploring the Barrio Alto area. Definitely prepare for walking hills (sneakers!), but that's anywhere in Lisbon. The huge two balcony windows were incredible for getting great air in the apartment. It could be a little noisy, but that's just the price you pay for being in a location with lots of restaurants. It wasn't like it was a heavily trafficked street, but the noise of whoever was down on the block seemed to carry up to the windows. But just to be clear, that was no issue at all compared to how nice the location and the apartment were.
Everything was clean and the hosts were amazing, so communicative and nice. They even booked a taxi for us to get to the airport when we left!
Would definitely recommend this place to anyone wanting to explore Lisbon =)
