As someone who has travelled through Delhi about once a year for almost a decade, this hotel is an absolute godsend. It is the only decent mid-range option that I know of in the city. The hotel's high ratings are absolutely merited. However, it is worth mentioning that the hotel's high ratings are because it is such a fantastic value, not because it is one of Delhi's fancier hotels.
In the end, this place is an amazing value for the money you pay, especially in a city with very few decent midrange options. Out of curiosity, I looked at some of the reviews on here that were not "Very Good" or "Excellent." Basically, what most of them boil down to, with one or two exceptions, is that people were annoyed that they weren't getting a 5 star hotel--a full service restaurant, an extensive breakfast, a legion of fawning staff--even though they are paying a 2 star price. If you are looking for something really fancy and with lots of amenities, then look elsewhere--and expect to pay four or five times more. Compared to other Delhi hotels in this price range, this place is amazing.
Bloomrooms is clean, modern, and well run. The staff are very nice and helpful. When I arrived, one of the staff was offering to help a guest by calling an airline to help sort out her travel arrangements. The rooms are modest sized, but perfectly adequate. The furnishings are minimalist and modern, perhaps too much so for some tastes (not mine, I think the decor is great). The bathroom is extremely nice--probably the best hotel shower you can find in Delhi that's not at a 5-star hotel. The Wifi is very fast. There are also a lot of really nice touches that I've never seen at a mid-range hotel in India. The room keys are key cards, and when you arrive they come in a small sheath that has a small map indicating how to get to the nearest Metro stop and how to get here driving (it's a bit confusing). There are water coolers in the hallways and water bottles in the rooms so that you can fill up on water, and in the morning there is tea and coffee on each floor. The hotel is immediately across from a really busy flyover, and I was really pleasantly surprised at how little of the outside noise one can here, even from a room that directly faces the street.
The breakfast is probably a bit pricey for what is offered, but I'm not sure that I've been to a hotel where that's not the case. In any event, the breakfast--while not lavish--is more than sufficient to start out the day, and the cafe also gets the job done for a mid-day snack or coffee.
The location of the hotel is also quite good. The metro is an easy walk. Defence Colony Market is also about a 20 minute walk, though it's probably a bit tricky to find for first time visitors. Khan Market is only 2 stops away on the Metro. The hotel is also located quite close to a taxi stand (near the Eros Cinema), and hailing an auto is pretty easy.
It's true that there is not a full-service restaurant, though the cafe can order food from it's sister restaurant in Defence Colony. That being said, there are several restaurants within literally a 5-7 minute walk, so it's not as though finding food involves a prolonged trek.
If I had to come up with a complaint, it's that the rooms don't have closets. There are some hangers that one can hang from one the mirror's in the room, but if you have lots of things to hang up, it's not ideal. But, since I imagine most people passing through here are tourists, that's probably a non-issue for most people.
I've already been telling colleagues who come to Delhi for work about this place, and they share my surprise and excitement about such a great mid-range option.
