I stayed in the Carlton hotel Budapest because of it's proximity to Chain Bridge and Buda Castle. It's not a 4* hotel in my opinion. The staff are very good, and the location is fantastic - but it lacks that special something that a 4* hotel should have. Having said that, it's a great hotel to make your base. The room was extremely clean and the housekeeping staff were good.

stayed at the carlton because of its location close to chain bridge and the old buda side. the rooms were basic but clean and adequate for the amount of time we spent in them, Breakfast was usual mix of continental ,rolls cheese ham etc and scrambled eggs , cereals . safe in rooms which i recommend you use.

We stayed at the Carlton in Dec 2011. I think this is a good hotel for the price but it should be considered a 3 star by American standards.
Great breakfast & attentive staff.

Truly, when we booked this hotel, we thought the name "Carlton" would involve some extra quality above the average. But it wasn't. Carlton Hotel Budapest has 4 stars but it deserves 2 and a half, no more.
Briefly: rooms are a bit small. But it's clean. The worst part is the bed as every room has 2 small beds put together, as we were told by the unfriendly guy at the reception desk.
Breakfast is the best thing of the hotel as there are many options... except sweet things!! 4 different cheeses but no cakes, any of them! I called this the salty Budapest breakfast.
Location is nice for exploring the city, just in front of the Chain Bridge. We read on Internet Pest is better than Buda for hotels, but for us, location was more than ok.

Tip: In the main street, just exiting the hotel to the left there is a good cheap restaurant for lunch (Ildiko Konyhaja)
