The flat is perfectly located, very central and close to transport infrastructure, a good choice for exploring the city. Clean, spacious, well-equipped, had everything we needed for the group of 5.
Yes, the staircase is steep and barely accessible for people with reduced mobility, but that is the case with all old buildings in Amsterdam and was not a problem for us.
The host was flexible about check-in and check-out, the communication was rapid and informative.
