The apartment was exactly as described. It's small but still quite comfortable for 2 people. It was exceptionally clean which was a huge advantage over some of the previous airbnb experiences I had before. Apartment is located in very quiet and safe neighbourhood with a few shops nearby.
Dacian was very helpful and very kind, responded to my every message. We didn't meet personally but he was very responsive on airbnb. He didn't mind us checking in a few hours earlier.
One thing that you should consider - this apartment is quite far away from the city centre. It'll take up to an hour to get to most of the tourist places and you'll have to switch between train and underground. It wasn't bad but you have to plan beforehand if you need to get somewhere on time. Fortunately there are ~3 train stations nearby and there are plenty of connections to choose from.
I highly recommend Dacian's apartment for the price.
