We stayed here last year and we're so impressed we would have stayed again this year but it was fully booked.
The rooms are immaculately clean and comfortable and the breakfast which is served is plentiful and beautiful. Can't fault the owner of this lodging- so approachable and friendly. He gave us loads of information about the local area and helped us with our bags.
The place itself is a little hard to find as it's within a block of apartments but location wise, it's really convenient to the main hub of Split. The only other thing to bear in mind if booking is that they only take cash for payment.
I stayed at the Supreme Spalato in Split this August and was really happy with the experience, the host is really accommodating and made sure I found the property well, and offered really reasonable transfers to the airport (which I would recommend as taxis are expensive) the room itself was very clean and comfortable and, given how close it was to the centre really quite at night.
It was reasonably priced and definitely value for money.
I would recommend the Supreme Spalato to anyone wanting to explore Split, but didn't want the informality of a big hotel.
