Had a very pleasant stay at Thiago's Airbnb. The location can be perfect *depending* on what kind of stay you're looking for. It's very central and puts you in the middle of the busy city streets, which is great as you're close to a lot of restaurants and shops. If you're looking to experience nightlife, you are also a 5min walk to the bars and clubs of Bairro Alto. You have a nice window that overlooks the busy street below, and can see a bit of the river as you look to the right. The room itself is very clean and tidy, with a big comfortable bed perfect for two people. There's a clothing rack with hangers provided as well! You share the kitchen and bathroom with 2 guys who mostly kept to themselves and were very quiet during my stay. They were more than willing to help with questions around the Airbnb, which I appreciated a lot! Thiago himself was very communicative and welcoming.
Some things to consider: since the location is central, it will be very noisy and hectic right as you step outside of the apartment, which can be an issue for someone looking for a calmer area to be in. The windows in the room is shockingly good at reducing the noise outside though! The apartment is on the 5th floor of the building with no elevator, so be prepared to climb stairs after battling some hills. The key can be difficult to use with the door as you need to do something special while trying to unlock the door. Don't worry though, Thiago provides a video tutorial on check in that you can rewatch if you get stuck like me!
