Have not been to the Elena apartments since 2006 so slightly out of date, but as only one review thought that an old one was better than none !
Nice apartments - basic. Usual heavy Greek pine furniture, two equal sized bedrooms, small functional kitchen and bathroom, communal space disappointing - small square hallway with table and chairs in it. Balconies are variable - some massive, some narrow and long. At the time I stayed there was not a pool, but understand that one is being put in. Given space available however it will have to be small. Not a problem the nearest pool is at the Philoxenia Studios; large and well kept -just a very small stroll away - however 25 yards along a busyish road with no pavements - so not ideal for children to walk on their own. In fact the Elena does not really have any public spaces at all, use the Philoxenia for everything, including safety deposit boxes and bar/food/swimming etc.
The main drive up to the Elena Apartments was sloping, but not steep. However Paleo as a whole is not ideal for people with limited mobility as very steep in places. If you are particularly agile ask for the top apartments as these have the largest balconies (however one is also used as a gangway for the other top-floor apartment) so swings and roundabouts.
Location - quite a way from the harbour down busy windy road with no pavements. However 4 -5 excellent tavernas nearby, and supermarket and bureau de change (both in supermarket and at campsite alongside) very close by. Swimming off cliffs at bottom of lots of steps.
We went with smaller children 6&8 - fine for them but teenagers may have been bored. Paleo is a very quiet place in comparison to the bigger resorts - and very spaced out. But this was ideal for us.
Car hire would be beneficial - but main bus to Corfu town stops outside the apartments if you prefer this.
If you do hire a car try George (Paleo institution - hard to miss) good cheap cars, get a smaller one - the road from Paleo to Lacones is better with a smaller car. Try trek to Angelo Kastro and Arillas over the mountain. If hiring car, park it in under the swimming pool area at the Philoxenia Studios - and keep it cool !
If looking at the picture of the Philoxenia Studios on the Kosmar site/brochure the Elena Studios can be seen to the back right of the picture -so shows how close it is to the pool - and the pool bar (which is regularly open late)
If I did not now have 3 children I would return here like a shot as it is good value for money, unfortunately it has a max capacity of 4 so am out of luck.
