I had to stay in Rio for 8 nights as a personal support staff of a Paralympian. I chose Sugar Loft and bang! It was my best choice.
The view was stunning!! Watching Sugar Loaf everyday from my room made me so feel so relaxed. The room is exactly as it is explained. Clean and spacious for a solo-traveler. Having a big fridge and a washing machine is certainly a big plus for a long stay.
Yes, the slopes are so steep --- nice walk down to subway Gloria station but very tiring uphill --- never try to walk up the Escadaria do Selarón and back to Sugar Loft unless you are an avid walker --- but as everyone says taxis are cheap and safer option. Usually less than 10 Reals from Gloria back to Sugar Loaf, around 12 from Cinelandia or Catete, and 25 from Bodafogo. I took yellow taxies and mostly were fine, except for just one driver who intentionally didn't make the meter work and asked for 15 Reals from Gloria. Otherwise the neighborhood was very nice, quiet, and kind. Every morning when I walked down the hill people greeted Bon Dia, and when I had my phone hanging from my neck (with a long strap) a man warned me I had to be careful!
The manager Amelia, with her beautiful English, was so kind and prompt. I could easily contact her via WhatsApp. She tried to accommodate my request as much as possible. I had some troubles with clogged toilet (which was my fault) and internet access but she trouble-shot immediately. Without her I couldn't have such a wonderful experience. Actually I had to change my rooms whilst my week-long stay due to air conditioner problems but Amelia handled it perfectly, and even gave me an upgrade to a bigger room with a terrace, which was stunningly beautiful but a bit too big for a solo- and not-vacation traveler since I was not in my room during daytime.
Oh there is no elevator so beware if you have big luggage or trouble walking up/down the stairs.
If I have another chance to visit Rio, hopefully on vacation next time, I shall DEFINITELY choose Sugar Loft. Muito Obrigado Rio, Muito Obrigado Sugar Loft!
