A small 4-star hotel on Lake Siutghiol in southern Mamaia, with a lake-view terrace, balcony rooms and the beach about 300 m away.
Hotel On Plonge Junior is a small 4-star hotel, built in 2014 and open all year, set on the shore of Lake Siutghiol in the Debarcader area of southern Mamaia. The beach is about 300 metres away, and the Aqua Magic water park and the cable car station are just a few steps from the door. The centre of Constanța is 5–6 km away.
It suits couples in particular, and anyone looking for a quieter base by the sea, away from the bustle of the resort centre. The six room types range from city-view doubles to balcony rooms facing the lake and suites with a bathtub and sofa bed, all with air conditioning, a minibar, a safe and soundproofing. Only the double and twin rooms with balcony face the lake, so it pays to choose carefully.
The hotel has a restaurant with a bar, a lake-view terrace where breakfast can be taken outdoors, room service, a 24-hour front desk, a lift and a gym. WiFi is free, and parking is public, on site, with spaces allocated subject to availability.

The double and twin rooms with balcony look straight out over Lake Siutghiol, and the hotel terrace, which also faces the water, is where many guests have breakfast and gather in the evening for the sunset. It is the most appreciated side of the hotel: a calm view across the lake, just a few minutes' walk from the Black Sea beach.

The two types of suite are the hotel's largest rooms and the only ones with a bathtub, a seating area and a sofa bed alongside the super-king bed, so they sleep up to three. One has a balcony facing the city; the other makes up for it with large windows and plenty of natural light. They are the obvious choice for a small family or anyone wanting more space.

The hotel stands in the Debarcader area at the southern entrance to Mamaia, quieter than the centre of the resort. The beach is about 300 metres away, Aqua Magic and the cable car are a few steps away, and city buses stop nearby. As a small hotel open all year, it has a 24-hour front desk and a gym, both handy out of season too.
Hotel On Plonge Junior stands on Bulevardul Mamaia, in the Debarcader area, on the shore of Lake Siutghiol at the southern end of the resort. Mamaia is a sandy strip around 8 km long between the Black Sea and the lake, and the public beach is about 300 metres from the hotel. The Aqua Magic water park and the cable car station are just a few steps away.

Guests particularly praise the friendly staff, the cleanliness, the lake view with sunsets from the terrace and the breakfast, as well as the short walk to the beach. The comfort of the rooms is also highly rated.
