Good points:
Check in staff very welcoming.
Good location - walking distance to metro, tram and some main city sights (Budapest is beautiful!).
Kettle, tea/coffee and fridge provided.
Not so good:
Mattress was very worn - one side of the bed completely caved in and very uncomfortable.
No mattress protector so felt less clean.
Towels very small and a bit worn.
Room quite warm and air conditioning not very powerful.
Attention to detail poor - broken shower hose, soap in bathroom not refilled (completely empty).
Be aware when booking the Expedia uncheckes the breakfast add on if you select a non-refundable rate. This meant that despite thinking I had paid the extra for breakfast (had selected the add on), the hotel did not have record of this and wanted more money than it would have been pre-booking. Expedia denied this. I therefore went elsewhere for breakfast.
