Spent 4 days with my partner at the Bloomsbury Hotel in July 2014. Overall we had a very good stay and found the staff to be friendly, pleasant and generally amenable.
We arrived early in the morning and as a GHA black member they let us check into our room early. The room, (a Deluxe) although nicely furnished was very small with no storage space. I asked if they had a room with a bit more space. They said they couldn't upgrade me as they didn't have a room for my entire stay, but they did, very kindly, find me a Deluxe room with a lot more space, which was much nicer.
Unfortunately the next day, we had some plumbing issues: after running the shower for 30 seconds it was evident the water was not draining and it started to flood the bathroom. I reported it to the front desk and they said someone would come straight up to fix it. However when we got back to our room late in the evening it was evident that nobody had been to fix it and the following day we had to endure very short showers and a bit more mopping up the bathroom floor! Again reported it and this time they sent someone to fix the issue straight away.
Breakfast in the hotel restaurant was very good - if you book with the reception desk the day before you save over £5 per person.
Despite the shower issues, it was a good stay and I would go back.
