We really liked this apartment! It had a nice interior and a great location. It was also very clean and had everything we needed plus a water filter which was nice. The only thing that was a bit annoying was the loud bar just right outside the apartment, but with some earplugs we were fine. We also stayed there over the weekend, so it might be different during weekdays.
Other than that, you could walk everywhere we needed and the area was really nice. The communication with the host was also great! Would recommend this host to anyone visiting Lisbon for a few days. :)
