Great stay at João's place last week. We arrived early and he was flexible with letting us check in. We had 2 small kids with us, 3 and 8 months, so this was really appreciated.
Location is fantastic. Close to everything and all the public transport links.
It was particularly hot and there's no air con, can get quite loud with the windows open but that's the price you pay for such a brilliant central location .
The apartment has everything you could possibly need.
Wouldn't hesitate to recommend.
