Maxone was my final choice, and it turned out to be the best.
The building offers aesthetic indoor and outdoor spaces. There's a very comfortable rooftop cafe, so you don't have to go outside to hang out; just go upstairs. The room is compact, just enough for me, as long as it's clean and everything works well.
The location is in the city center; Tunjungan Plaza is just a short ride away. There are plenty of legendary eateries around the hotel.
Highly recommended for those looking for a hotel in the heart of Surabaya, on a budget but comfortable.
BEST VALUE FOR MONEY.
Just a small suggestion: the breakfast is mediocre, but for the price, it's okay.
