Thailand is a busy place and the traffic is terrible. We had a 1 year old with us and because the Adelphi Grande is within walking distance of the BTS Skytrain, we were able to get around to the main areas without too much trouble, although beware if you have a pram with you - you'll be lucky if you find a single lift outside of the hotel or large shopping complexes.
The hotel is also opposite the Emporium shopping complex (again walking distance) and there is a supermarket within 300 metres.
The staff at the hotel were brilliant. They were very friendly and helped us with tours, transport and information.
The rooms are very clean and ours contained a washing machine, microwave and a hob so we had everything we needed to look after our daughter without hassle.
The breakfast was very good and with a reasonable choice of food.
