Sekai Hotel was perfect for what I needed: a place to sleep and keep some stuff while I explored Osaka. It is a great deal, close to the subway and tons of shops and restaurants, and got the job done.
I absolutely loved the staff working there, notably Ayano who had helped me familiarize the key areas of Osaka. The cleanliness of the hotel is superb. It is so close to the Kintetsu subway, maybe like 3 minutes? AC was strong during my stay in July. Toilets are very high tech haha and shower stall feels very new.
