The Mandarin hotel is really classy. Elegant, nice interiors, attentive, friendly and helpful staff. Probably the best wifi I found during my trip in Asia. I didn't use the swimming pool, but it looked very good. The massage centre is really good as well. As soon as you get inside the hall, you find relief from Bangkok's hot, traffic and confusion. The room was very nice: with large tables, fridge and a microwave, which is really helpful, if you get takeaway food, for example. I really enjoyed the bathroom and the funny small computer for intimate hygiene. Definitely a recommended hotel: the best I stayed at in Bangkok.
