We were a big group of people staying at Romana's. The staff was very friendly and helpful and we ordered the car transfers from and to the airport via Romana.
The apartment was very spacious. Romana also answered quickly to every message. The apartment was located right in the centrum, but not in the busiest tourist streets, which was very nice.
The cons were that we reported about a broken sink and a toilet seat but the maintenance didn't come to fix it during our stay. The biggest con was that some of the guests got very big and itchy bites during the night, and we suspected that they were from bed bugs. We sent photos to Romana, but haven't heard of her or the staff after.
