Ana's and Hugo's place is very well located - next to one of the stations were all routes and different sorts of transport cross - buses, metro, trams, boats. This makes it is easy to find and navigate throughout the city.
Cons might be, that flat is quite small and in some spots ceiling is not comfortable for taller people (~180cm).
All in all, we enjoyed staying here and want to say special thanks to Ana, who was always very helpful, did not count her time and is a truly dedicated host.
