The apartment is great and spacious, although there is no living room. The AC was welcome.The are is very safe. You will need to take a train for a 5 mn ride to get to the old city.
For some strange reasons (taxi lobby I imagine), there is no uber or equivalent. A taxi will take more than 60 euros to bring you there, only 4 km away so make sure to come back by train before 1 pm
