Domodedovo is not bad. Its big, clean and has many check in desks. The food is expensive and can of beer will cost you about 250 rubles. A basic salad will be over ten pounds. The the down side is it takes ages to get to and to leave the airport by taxi. The police hang about outside the airport and will not allow cars to park there, so being collected by taxi will be hard since they often can't park. You will also be hassled by countless men offering you a taxi, be careful you could be given a city tour and charged 1000's of Rubles. The airport in summer was hot this year and the air con was not working so it was hotter inside than outside. Perhaps the air con units were never installed or were stolen? nothing would surprise me here. Watch out for pickpockets and hold onto your things, most of the police look uninterested in their jobs and mostly sit about smoking and I have even seen some buying beer from the airport shop.
Generally its a good airport but allow at least two to three hours to get there if travelling from the centre of Moscow.
