I have stayed at Hotel Moti twice now, most recently in november 2010. The reason I went back to Moti is, of course, for the delightfully efficient and most helpful Raj - the owner and manager of the hotel.
The hotel is an old mansion that has been converted, consequently the rooms have been built into the existing structure, which gives a homely ambience, with some delightful colonial era details. Bathrooms are standard - not perfect, but funtional, with hot water (may I add running water 24/7, unlike quite a few other budget hotels/hostels in Mumbai) and flushing toilet. The beds are comfortable, with sheets and blankets provided (also unusual for budget digs in India). The area the hotel is in is very quiet, leafy and dotted with beautiful old buildings, but close to all of the tourist attractions that Colaba has to offer. Stepping out of the hotel and wandering the neighbourhood streets of Colaba was actually what I enjoyed most during my stay there. I slept very well every night of my stay.
Raj is very conscious of making sure his guests have a safe and pleasant stay in Mumbai. Shopping, eating, transport, tourist and any other enquiries are always welcomed by Raj, who is always happy to share his wealth of knowledge about this city. I have only ever found the staff and Raj polite and courteous, and am surprised at the review written by Belfen.
For those who have criticised the hotel for cleanliness I can only say, having travelled India extensively the past 12 months, I have seen far, far worse. Anyone expecting a western style level of service and cleanliness in budget hotels in India will, of course, be disappointed. If gleaming bathrooms and daily room service are more your cup of tea, then unfortunately you will have to pay more, especially in an expensive city like Mumbai.
