This is an ultra modern, well run hotel with friendly staff, the star of the hotel is NUM, from meeting and greeting at breakfast to cleaning the rooms on the 2nd floor, my room included! He was so friendly and helpful and did a fantastic job in cleaning my room, nothing too much trouble for NUM , he and the rest of the team made us feel welcome, my room was clean but small , breakfast was good , can buy beer and soft drinks in reception which is good , stayed for 4 nights, 1st time in Chang mai but not my last , I will definitely stay again at sleep mai , highly recommended, thank you again to NUM and the helpful staff at sleep mai
