This was an excellent apartment for three of us centrally located for tourist activities. It's near the Acropolis museum, the Acropolis entrance, tons of restaurants, shopping and other sites. Upstreet provided information for cab service from the airport called Welcome Pickups. It cost 52 euros -- an extra 6 euros v. just getting a cab from the cab stand, but the driver met us, spoke excellent English and had many tips about where to go and what to do in Athens. Check in was very easy. Directions for finding the lockbox around the corner from the entrance were clear and simple.
Once you enter, you come up half a flight of stairs. There is a small elevator you can take to the second floor (third floor in the U.S.) Helpful for luggage. The apartment is exactly as shown in the pictures. Simple, comfortable living/dining area with airconditioning. Small well-equipped kitchen. Two separate bedrooms each with a queen bed and its own airconditioning. It was very clean and easy to use. There were several shops on the same street as the apartment just a block or two away to get groceries. Restaurants and bakeries around the corner on Vekou Street. We had a great breakfast at Vanilla. It was maybe a 5 minute walk to the Acropolis Museum and all the restaurants going up the hill on Makrigianni. There is a place to leave luggage a few blocks away at 3 Vekou Street -- large locker that held three carry on suitcases and a couple of backpacks for 8 euros. We would recommend this place to anyone looking for a simple, clean, central apartment in a safe neighborhood in Athens.
