excellent servicedelicious foodideal locationeasy return
The staff provided excellent service throughout my stay. Breakfast featured delicious food and drink options. The location is ideal. It is conveniently situated within walking distance of major attractions and the metro. I would happily return to this hotel again.
I noticed the room lacked a full set of drawers for clothes storage. Instead, there were just a few small, single drawers dotted around.
