I thought our credit card reservation through Booking would pay for the room, but we ended up having to pay in cash when we arrived. We had enough cash, so that was OK, but it would have been good to know that the credit card just held the reservation and full payment in cash was expected upon arrival. Also, this isn't necessarily a bad thing (because the apartment we had was great), but the inside of the apt was not in any of the pictures on Booking.
The apartment we were in was number 15 on Radunica. It was about 2-3 minutes (walking) to the palace area (where all the bars, restaurants, shops are). I expected this apartment to be located in the palace area and was surprised to find that it wasn't, but it was extremely close, so it ended up being fine. The inside of the apartment was very nicely furnished with a modern style, was clean and very spacious. It had a queen bed, living area, kitchen and bathroom. Plenty of space for me and my husband to spread out and be comfortable.
Antonia met us at the apartment and had a map of the area ready for us, with restaurant and bar recommendations already noted.
Something I should have realized beforehand but didn't was that Villa Spaladium I think is actually several different apartments. It would have been nice if the pictures on Booking identify which apartment is being shown. That way, when you are assigned your apartment, you can tell which photos reflect that space. That being said, our apartment was really wonderful and it was our favorite place we stayed during our entire trip. I feel confident recommending "Villa(s) Spaladium" to other travelers.
