I just had my surgery back in November 1st. I stayed at the Bangkok Rama Hotel for the rest of my stay. It's basically like studio cottages and you have your bed, bathroom and kitchen to cook as well as a menu for ordering food. I stayed there for 21 days and it was great. I had the a/c on most of the time and had a patio with benches next to the entrance of my room. There were a few other girls there who was either there longer or just had surgery done. Although, a few others have had a different experience there but for me, it was cheaper and saved me a lot of money.
As for wifi, it went great for me. It wasn't slow or choppy but i wouldn't say it was better than the internet in America. I was able to skype and play my online mmorpg games while in recovery at the bangkok rama hotel. I ordered room service a lot at the last 2 weeks of my stay there. I walked around the hotel as well to exercise.
But I think you could stay in the tower but the cottages/bungalows are recommended for surgery patients from Dr Chettawut. Ms Sri and another nurse always visit daily but not on sundays to check how your vagina looks either if it's infected or if something is wrong and if there is, she reports it to Dr.
On my last week when I thought I felt better which I almost fainted, I went to walk around and had to take out cash from an ATM and there were shops and a 7-11 as well as the supermarket 4 blocks away where i almost fainted but thank to my neighbor at the bangkok rama hotel, she was there to help me.
I brought about $17,500 and after I had to pay for the SRS+BA surgery (444,000 THB/$13,586) and skin graft (32,000THB/$980) and since I wanted one size bigger than the standard size for my BA, I had to pay $300 more, $3000 went for my excess grocery shopping, room service, total hotel payment, free breakfast everyday, extra hygiene supplies and pads, and plus the extra fee for taking money out of the atm that they charge to your bank.
