The Arnoma was a ideal for travel with a small child. The rooms are spacious and I got two with connecting doors. The Arnoma is located in a nice part of Bangkok, opposite the Central World Mall though I found that mall rather pricey. Ther'so a 7/11 mart just next to Arnoma and a cross the road via the skywalk you get excellent street food, shrimp with rice which my 10yr old couldn't get enough of, shwarma, also some fast food places. Arnoma is a few metres from the sky train station so you can catch a train to MBK Mall which had great offers on clothes :) Arnoma is also a short walk to the boats where we opted not to take the tourIst boat rather we got on the regular transport boat and got off at another mall that had some activities for children. It was easy getting the train to Chatuchak weekend market and on weekdays the Park and Children's museum were no cost options for a day out! BeWare friendly women offering "advice" that such and such place is closed - it's a con! We were told the Children's museum was closed and the park too but good thing we had checked online and both were open - no entry fees!
Back to Arnoma, food options were OK though only had breakfast - they had continental as well as other options - rice, chicken, noodles...
The swimming pool was small but ok.
Spent more time outdoors than in the hotel :)
