Villa owners were very helpful before we left the UK in providing information. We arrived at Varna airport to be met by driver who were very friendly and helpful. We followed to the villa in our car hire. Had a quick tour of the beautiful villa then the owners gave us a tour of Balchik - well worth it.
The Villa is well equipped, although there was only the four of us (girls aged 8 and 11) the villa is spacious enough for 2 families with kids, or a family and grandparents. Five very large double rooms with Queen beds, suitable for kids or adults, travel cot. Well equipped kitchen, large kitchen/dining area.
We liked the shower room/loo downstairs as well as the bathroom upstairs as it was great to use during the day. The pool is lovely, sunbeds included cushions and there is a lovely tree in the corner providing much needed shade if it gets too hot for you!
You don't really need a car as you can walk (down the hill) to the Palace/botanical gardens and either dine/shop there, or get a taxi to Seaside lane (promenade) at Balchik - for only £2 - £4. We hired a car so we could drive to Albena and the excellent waterpark, Acropolis at Golden Sands (20 mins away - can get taxi there).
Lots of lovely restaurants to choose from and spend a lovely evening watching the sun go down. Bulgaria/Black Sea Coast is beautiful and the people are very friendly. Its also amazingly cheap at the moment to eat out, shop etc. We would highly recommend Rosa dei Venti as its in an excellent location on the Black Sea coast.
