The rooms are spacious, impeccably clean, and designed with modern aesthetics that offer a cozy yet elegant atmosphere. Waking up to the stunning views of the lake each morning feels like a dream. The quiet surroundings ensure that your stay is as restful as it is rejuvenating. Families will find the hotel to be a paradise of convenience and enjoyment. The on-site facilities are thoughtfully tailored to cater to both adults and children, with something for everyone to enjoy. The playgrounds and dedicated family areas allow the little ones to have fun in a safe environment, while parents can unwind and soak in the beautiful scenery. We had an outstanding stay with stunning lakeside views, tranquil atmosphere, excellent dining, and family-friendly facilities. Convenient base to explore Mamaia's and Constanta’s attractions. What truly sets Hotel On Plonge Junior apart is the evident pride every staff member takes in their work. The team's kindness, efficiency, and professionalism created an atmosphere of genuine care that made our stay not just comfortable, but truly exceptional. Thank you to everyone at Hotel On Plonge Junior for making our visit so memorable.

The On Plonge Jr is a different location from the On Plonge. Jr is farther away from the old part of town and the casino, but the Jr is on the Ma Mamaia beach area and has beautiful views of the Lake. We took Uber to the old town, inexpensive. Lovely breakfast on the side of the lake, restful and peaceful, ducks and birdwatching.

Decent hotel but meet more attention to guest.

Good hotel. Nice lake view rooms on the back side. Front side faces the street which can be of concern do to road noise. There is a gym upstairs that is for members, not hotel guest. Gym members sometimes take up the parking. Also there were two days without hot water.

Dejligt hotel

Rigtig lækkert hotel. Udefra ser det ikke ud af meget ved ankomst, men kommer man indenfor så er sagen straks en anden. Venligt hotel, hyggeligt indrettet, lækker terrasse med udsigt over vandet hvor svaner og ænder svømmer rundt, rengøring er der intet at klage over, lækker morgenmad samt aftensmad der kan købes for rimelige priser og er lavet fra bunden, kort sagt, vi havde nogle dejlige dage der og kommer gerne igen

Mini badeferie i Romania

Vi hadde 2 netter på dette hotellet. Rommet er romslig med balkong og utsikt over innsjøen, nydelig solnedgang kan nytes fra balkongen. Nydelig frokost og hyggelig personale. Eneste som trekker litt ned er mulighet for kaffe og te i rommet. 10 minutter å gå til sandstrand Mamaia, men det er mye sjøgress og vannet er ikke rent. Bedre badeforhold i Tuzla beach som ca 45 min med bil fra hotellet.
