overall the apartment is comfortable, ok location and exactly like the photos. there are lots of hills around, but this wasn't a problem as it's still walking distance to attractions. there were some good restaurants nearby, squares and mini markets, so quite convenient.
the main downside was the power cuts whenever we used more than 1-2 electric items at the same time. energy dropped when using dishwasher and hairdryer, or using kettle while cooking on the hob, or more than 1 ac at the same time. it wasn't pleasant experience while cooking at all, as energy cut off all the time if using more than one utensil. so if staying for short periods with no cooking, might be OK. but if you stay longer and intend to cook, I would not recommend unless the problem gets fixed. we stayed 4 nights.
at night it was also a bit noisy in one of the bedrooms as walls are thin and share with building staircase and street.
