Marcelo's place is perfect for stay - it is situated near central station from where you can reach anywhere. The flat itself is nice, clean and spacious. It has all basic stuff needed (e.g. kitchen appliances).
The only slight drawback is his communication that it is quite often not clear what is required due to his knowledge of English. However, it relatively minor and is overwhelmed by all the other pluses.
All in all - definitely recommend for stay.
