We were able to camp a bit during our short time in Greece, though most of the campgrounds were not fully operational as we were there in March (most campgrounds do not appear to really open until at least 1 April). The days into and out of Greece were at hotels selected for their easy access to or from ferry ports.
Patras (by ferry from Ancona) – Galaxy City Center Hotel, 9 Agiou Nikolaou Str, Patras. We paid 65 euros for a double room with ensuite, fridge, no breakfast. The room was clean and decent size and appears to be relatively new (or newly refurbished), and had a lift. Bikes were kept locked in the lobby area under the stairwell. There was supposed to be free wi-fi available throughout the hotel but it was not working and we couldn’t get the night manager interested in trying to fix it (we complained at checkout and negotiated 5 euros off the room rate). There are some other hotels in this city that may be a better bargain but we arrived late on the ferry and knew this one was supposed to be decent so we quit looking.
Akrata (80k from Patras) – Campsite Blue Dolphin, signposted along the old road. We paid ~15euro for a tent site and the campground had hot water, showers, and toilets. It was not officially open so we probably paid less than the full rate. There was a café/shop but it was not open when we were there. Lovely spot though, right on the beach and very quiet. May be a different story if it was really full.
Korinthos (65k from Akrata) – Camped again, not sure of the campground name but it was right on the beach. The campsite was again one of those that was not really open fully but they let us camp – we were the only ones there. There was relatively warm water, warm enough for a quick shower anyway, and a small camp kitchen with power.
Piraeus (80k from Korinthos) - Phidias Hotel, 189 Kountouriotou St, Pasalimani, Piraeus (www.hotelphidias.gr). We paid 37euro per night for 3 nights (booked online) for a double room, ensuite, fridge, free wi-fi, breakfast included. Bikes were kept in a guarded parking garage across the street for 3euro a day (hotel has no parking). This turned out to be a great hotel – recently renovated so everything was fresh and clean and in good working order. It was really handy to the ferry to Turkey and there were some great, inexpensive eateries just a couple of streets away. The staff at the hotel were great – very helpful. It’s only a ~15min metro ride into Athens and you can get the hotel shuttle down to the metro station or walk about 15 minutes. Highly recommended.
