Taking a taxi in Mamaia is a smoth way to getting around. I took the taxi only once, and that was to the nearby town Constanta. It costed about 250.000 LEI, and I found out later that I payed to much. A more normal price should have been around 140.000 LEI.
100.000 LEI = 25 SEK = $3.25
The soviet build Ilyushin Il-18 from Tarom - Romanian airtransport took me from Oslo to Constanta, Romania. A noisy, slow, but interesting experience.
The buses are really modern and an easy way to travel in Mamaia. There goes plenty of them every hour to and from Constanta.
A more cheap way instead of the taxi, to getting around in Mamaia, or to visit the town Constanta is to take the bus. One way ticket costed around 15.000 LEI.
10.000 LEI = 2.5 SEK = $0.33
