I've just spent 2 weeks at the Redwall hotel.
I read dozens of reviews before booking my holiday and noted the comments about overall cleanliness, language issues and hard beds. I still booked and spent my 2 weeks in a western style executive room on the 3rd floor.
I found the overall cleanliness to be very good although there were the occasional odd smells in the lobby. I had no problem getting Wifi in my room and the speed was ample for my needs.
Language was destined to be an issue from the outset, and it was no worse than I expected. In my opinion, if people are going to find that a problem then they should consider a country that is a little closer to home. I managed to get by without knowing any Chinese other than please, thank you, yes, no, hello and goodbye. The rest is all part of the fun of the holiday. Smile, be polite and it's not that difficult to overcome most problems.
As for the hard beds, the reviews are spot on. I have never slept on beds as hard in my life! Having said that, after couple of days, I got used to them. As a positive, they did my back the world of good.
I thoroughly enjoyed my time at the Redwall and I would happily recommend it to anyone. The hotel staff are very friendly, patient and always willing to help.
