The owner was away during our stay, so we had the use of the whole flat.
We've been welcome by one of Aldo's friends. However, Aldo has been in touch with me for the whole length of the stay to make sure everything was ok and giving useful information about things to do and transports.
The flat is conveniently located for transports to and from the city centre and Amsterdam's main attractions. It takes about 20-30min by tram to reach the city centre.
