my family & I enjoyed our stay to this hotel. Though it’s a little bit far from the old town, there’s a bus number 116 if u want to go there . The hotel as well as the room is very clean. A water dispenser for free at the entrance is a plus . Surely if I’ll return to Warsaw, I’ll stay in this hotel ❤️

Meh. I think that’s my word. Not even a hi, welcome or a smile at check in. Just given a card and the word ‘8 floor’. Room is what you expect. Not much. The basic is covered but that’s all. Convenient for one night as I did, but not again. :)

We stayed at the O3 hotel in Warsaw this past weekend. We’d read reviews about it being a hostel and very noisy so we’re a bit wary. We need not have worried. The first 7 floors are hostel and the top 3 floors hotel. We were on the 10th floor and had no noise problems at all. The hotel is wonderfully clean and tidy. The rooms are your standard Premier Inn/Holiday Express type rooms. The shower/toilet was very tidy and clean and well appointed. Maid service was excellent. We ate breakfast there twice. There was hot and cold food available. The hot food was very tasty, but if you’re not adventurous then you’d be limited to scrambled egg and hot dogs. But when I’m Poland eat like a Pole. Reception staff were very helpful. A great base. 15 minute drive from the old town, the airport and everywhere else we wanted to go. Perfect.

Estadia

O hotel está bem localizado, a cerca de 6 kms mas mesmo ao de uma avenida que vai direto para o centro da cidade. Os autocarros passam quase de 5 em 5 minutos e é super rápido chegar ao centro da cidade. Os quartos são quentes e modernos, a cama é confortável. O pequeno almoço é à volta dos 7 euros mas completo.

Clean room - that's all good that I may tell about this hotel. I was extremely frustrated with their tricky, slow, and unstable internet connection (wifi). I wasn't able to accomplish even minor tasks. I may understand the dust and noise in the lobby due to a major renovation. But, the air conditioner didn't work and I couldn't open the window because the handle was missing.
