We were three adults staying two nights in Split in May 2016 - just after this charming 2-bedroom apartment had been fully renovated. Marina was super friendly and welcoming, took her time to share her insights into the city and was super responsive on her cell phone with any question we had. The place is tastefully decorated, modern, spotless. We loved the (mostly pedestrian) neighborhood and enjoyed coming back every night to the peace and quiet of the apartment.
Walking to the waterfront and to the Diocletian Palace was a pleasant 5-min stroll; everything you need to get in terms of supplies is within a 100-meter radius (bakeries, supermarkets, pharmacy...); and the fact that Marina has a free, secure parking was a huge bonus, especially so close to the Diocletian Palace. We just parked the car there and blissfully forgot about it for the rest of our stay!
Yes, you do have to climb stairs (one short flight up to the apartment itself, which has 2 levels) but that's part of the charm, and they aren't bad at all.
Our only regret: we didn't have time to try the wine and cheese bar, Paradox, just around the corner. Will have to come back for that one. Thank you Marina! We loved Split and hope to be back one day!
