Because Athens is so accessible by Metro, we don't recommend an overnight stay in Piraeus. However, if it makes sense in your travel plans, try one of the decent, moderately priced choices below (usually no more than 100€/$130 double). The 74-unit Hotel Mistral, 105 Vas. Pavlou, Kastella (tel. 210/411-7150), has a nice roof garden. Recently renovated, the 31-unit Ideal Hotel is at 142 Notara (tel. 210/429-4050). If you want something a bit nicer, try 32-unit Hotel Castella, 75 Vas. Pavlou (tel. 210/411-4735); or 74-unit Cavo D'Oro, 19 Vas. Pavlou (tel. 210/411-3744). Cavo D'Oro has a pool, but it also has a disco that can be very noisy. Frugal traveling friends who visit Greece every year always stay at 56-unit Hotel Triton, 8 Tsamadou (tel. 210/4173-4578), which they praise for its relatively quiet location -- and double-glazed windows that cut down what noise there is.
