After a hickup with check-in - which was quickly and graciously solved by all parties, in my opinion - everything from then on went super smoothly. The apartment is spacious, VERY well cleaned & kept and quite quiet, both of which are highly important points for me, and its contents are fresh-feeling. I slept very well, and am one of those sensitive to noise. Other than that, it's also very well equipped (only purchase was kitchen rolls, and there were a gazillion things I a) needed and b) don't even use) and even comes with really nice neighbors.
Mr Perdigão is a tough negotiator, albeit very patient, and him and his "local host" are a good team, with whom I felt in safe hands. A special thanks to the latter for his kindness. I'd gladly be back, if they'd have me.
