I traveled there solo for vacation and to conduct consumer research. Lemon Tree was ideal. They provided a personal car to and from the airport and when I needed to go into the city (about $34 USD). I called before arriving and a driver met me at the airport (this is a BIG tip for the solo traveler). Wonderful service and personal approach especially from waiter, Gaurav Jalia, who not only wrote down places that would be of interest to my research, but to ensure my safety, he personally escorted me to a few sites in the city that would benefit my study (even on the public bus). He went over and beyond the call of a server and became a friend who wanted me to experience India safely and discover the beauty of Bangalore's people and culture. Vel (at the front desk) also took care to make sure daily that my stay was comfortable, productive and safe. The morning and evening buffets had good choices of excellently prepared vegetarian and Indian food or you could order other varieties from the menu. My room was spacious and clean and a lemon scent was sprayed in the room to match the scent of the lemon toiletries. There were many regular business visitors there. Some travel there once a month. I understand why they return to the Lemon Tree because I will return there, too. The only less than ideal issue was that I had to pay for the internet. It wasn't expensive, but irritating. It's about 80 rupees per every 30 minutes.
