Great location in Colaba, close to Leopold café, the Prince of Wales Museum, and also within a short walking distance from major tourist attractions such as the Gateway of India, Horniman Circle, the High Court and the University of Mumbai, etc.
The rooms are clean and very reasonably priced for Mumbai standards, and they are equipped with AC and a plasma TV with some cable movie channels. Hot water is abundant.
There is free luggage storage on the day of your check-out. Unfortunately, the YMCA Central Branch does not provide internet, but there are internet cafés closeby. Table tennis players will be happy to find several ping pong tables at their disposition.
The price range is similar to the YMCA International House in Mumbai Central, with the difference that at the YMCA Central Branch in Colaba you are not obliged to spend the 800 rupees per day for breakfast and dinner, and instead you are free to have all your meals outside which is very useful given the abundant eating options in Colaba. If it is more convenient for you to stay in Mumbai Central, however, the YMCA International House is a great option and its rooms offer a slightly higher standard than those of the YMCA Central Branch in Colaba.
