Stayed in Pearl Plaza in February 2011 for 3 nights while in Delhi. I travel a lot and frequently stay in hostels and budget accommodation - but this hotel is one of the worst experiences so far.
We arrived in Delhi early at night (about 2 am) and hotel´s driver met us at the airport. That was a very nice beginning. Upon arrival at hotel we found staff sleeping on the floor at the so-called lobby. It hardly looked the same lobby that´s shown on their web-site. But that was still OK, no worries. The problem was the room.
Our room was spacious and looked well-furnished (LCD TV on the wall, nice bed-covers). But it was extremely dirty. It was definitely not cleaned for longer period of time - including after previous guest. There were rolls of dust on the floor, the toilet bowl was stained with somebody´s pee with yellow liquid inside, the shower dripped, there was dirty paper on the WC floor, trash-bin was still full of trash etc. We checked the bed-linen and these were very dirty and stained, there was hair on the sheets - the linen looked like it was used and left unwashed. We complained the hotel staff about the problems with the rooms and politely asked to clean the room or give us another one. They were sleepy and didn´t bother too much, promising to clean in the morning. We demanded the manager (I guess he was the manager - he was the one in reception) to check the room and after that one guy cleaned the room. We asked for new sheets as well and were firstly said there´re no clean ones in the hotel. Finally the found some new bed-clothing - but it didn´t look promising as well. Finally we slept all three nights fully dressed. And all this happened in the middle of the nights - we haven´t slept for more than 24 hours and were expecting nice rest before exploring the city.
After getting our room cleaned we planned to take a shower - but no hot water was provided. Staff said it was due to late hours - but there was never any drop of hot water during our stay - was only cold and ice-cold. So we just showered in cold water.
The room itself was very cold. I know that in February nights in Delhi are not warmest ones and we were prepared with warm underclothing and wool socks - but this was just too cold, like staying outside. I understand that there could not be heating in India - but there were no warm blankets as well. There were only two thin ones and we were said they don´t have additional ones to give us. They didn´t clean the room any more during our stay and we had to ask the reception even a roll of toilet paper.
The breakfast was served in our room - we had omelette, tea and toast for breakfast.
We liked the neighbourhood - it was crazy and noisy and smelly - but it was fun and very Indian. There´re small markets near the hotel were one could buy snacks and drinks. A money-changer was right opposite the hotel. There´s a short walk / even more short drive from the hotel to the railway station. Don´t ask the hotel to arrange a railway station drop-off for you - the price is absolutely unfair. We asked the staff if we could find a rickshaw at 5AM and were suggested to take a taxi as there could be shortage of rickshaws at that time. So we asked for a taxi - but received a hotel driver for horrific price. As we were really tired of arguing and were in a hurry to catch our train we used the service. Actually there were plenty of rickshaws on the street.

In general that was very bad hotel experience. We were really considering moving to another place - but we booked through HotelClub and the full fare was pre-paid. This was the first time ever I considered changing a hotel.

I would be satisfied if I paid 10-15 USD for night. We paid 42. And that was a real rip-off for the quality received - a dirty room without hot water. Totally overpriced.
