We stayed at Boscolo for 2 nights and while it was a lovely hotel, I felt that it could do with a bit of a 'facelift'. The lobby, while grand, felt somewhat dated - it looked like it was designed in the early noughties. Our room was nice and clean, but didn't feel particularly luxurious.
The New York Cafe is excellent though; we had a great meal there.
Would recommend this hotel to those visiting Budapest.
