We stayed at the top floor of André's apartment building for five nights and it was perfect. The apartment is spacious and in tip-top shape. New, clean, comfy and very well equipped. Not only all the kitchen utensils, a coffee machine (including coffee pads!) where there, André has even thought of an umbrella.
Rua Bica is a great area for nightlife. The bars on & around Rua Bica are a bit more sophisticated and less commercial than the ones you'll find in Barrio Alto (which is only 200m away). The street is quite noisy most nights of the week. And you can hear that in the apartment. Although thanks to the fact you're on the second floor and the building has double glazing, it's more like a constant buzz than like actual (loud) noise. The bedroom is in the back of the apartment and is even more quiet - we slept well without earplugs, but just bring a pair if you want to be absolutely sure...
André is a great host: he responded very quickly to any messages or e-mails we sent him, he knows his city, he leaves you be but he's there when you need him. One night at about 2am we had a minor problem with the lock of the front door. We called André and he was there in 20 seconds (literally!), fixed the lock, wished us a goodnight & went off into the Bica nightlife again :-)
Only downside we can think of is that there was no hook to attach the shower head to. But knowing Andre, he has already installed one 20 seconds after reading this review...
