The Taverna is a four star hotel with an enviable location on Budapests premiere shopping street, Vaci Utca. It is also 5 minutes walk from Deak Ter Metro station which gives you access to all three metro lines. There are 226 rooms in total, all with airconditioning. Facilities are fine, though the rooms could do with a fresh lick of paint (a redecoration programme was in hand last time I visited).
Buffet breakfast is normally included in the room price and is excellent. To be honest, you can skip lunch after you've tucked into the hot and cold fare on offer.
Service is pretty good and friendly, with a fairly young staff, most of whom speak either English or German.
The hotel is home to one of Hungary's best restaurants, the Gambrinus. Excellent Hungarian food, but a bit pricey (in Hungarian terms) if you have a tight budget. The Zsolnay Cafe (your coffee and cakes are served on the famous porcelain) makes a decent spot for a break. They also do an excellent all you can eat buffet lunch for around HUF 3000.
