I stayed at Aloft hotel in Dec2012/Jan2013 and overall it was pretty nice hotel, i would recommend it. It is lb friendly and doesn't charge a guest fee.
It's very modern and new, has a unique open concept design for the whole hotel. Honestly from the pictures on expedia, i thought it looked really weird, but it's much better looking in person.
The swimming pool is nice, and it has a gym.
the location was just ok, it's a very busy street with slow moving traffic, even the taxi drivers comment on how slow the traffic is there.
they do have a tuk tuk that can take you to nana bts, but you might have to wait 15 minutes for him to get back to the hotel.
there is a 711 just outside and some really nice restaurants down the street.
