This studio apartment is just lovely—it actually ended up being a lot more spacious than what I imagined from the pictures. Everything was super clean, wifi worked great, there were fresh towels and bedding, kitchen had all the basics, and for more sensitive sleepers there were blackout curtains and earplugs to block streetlights and noise. It's a fairly busy area even at night, but that was exactly what I was looking for so I was well pleased! Noise from neighbors in the building was nonexistent, so it's only the street you'll have to consider.
The location was perfect for my needs—not in a super touristy area, but still central enough to access everything on foot or via transit. It was a wonderfully short walk to catch the metro from Bolhão station to the airport—the purple line E goes straight there with no transfers! Though be advised, the station doesn't have much if any signage indicating the purple airport line, but rest assured it does indeed stop there! Check-in was a breeze and José was a very attentive and communicative host. Would have stayed much, much, much longer if I could!
