The apartment is very spacious and has everything you can desire (washing machine, dishwasher, iron, 2 TV, 2 A/C units, wifi, great kitchen, etc.). It's in a perfect position to explore the city by bus, subway or by foot.
Some minor problems I don't really take too serious (e.g. they prepared the sofa bed in the living room, while the bed in the single room was not prepared at all - despite our emails asking exactly for the opposite, being in 3 - then they said they will remedy next day and never showed up again, so we did it quickly on our own). It can happen even if it shouldn't when an agency (with strict terms) is managing things and not a private owner.
The only real problem was the noise. The double windows in the main bedroom don't filter out the rumors from the flower market below in the early morning, nor the general traffic noise during the night. During the day you have to close the windows if you want to conversate, watch TV, etc.
In case you are used to some noise in your usual habitat, this will be a great apartment to stay and I recommend it. In case you are usually living in a quiet village (like us) bring earplugs or look for a place in a less busy area.
