The City Plaza Hotel stands a half hour walk away from the Acropolis in central Athens, nestled in an inner-city alley amongst ageing apartment blocks. Few abnormalities can be registered from outside: the building’s windows emit dim light in the grey morning and clothes are strung along half the balconies on its seven floors. The one outlier is a banner that stretches across three balusters: ‘People are dying in the camps’, it reads, ‘Open Borders. Open Buildings.'
