There have been a number of posts about which hotel in Budapest. There are a lot of really wonderful hotels, and it all depends on what you are comfortable with and how much location is a priority and the cost that you are wanting to pay.
I got a question yesterday about a hotel that I had never heard of but the location was intriguing so I thought I would pay it a visit.
Called "Up Budapest". The location is catty-corner from the Hunyadi Square Market. The Hunyadi Square Market is one of the old market halls in town (there are about six in all). Not nearly as large and grand as the Great Market Hall, but more local. On Saturday mornngs the farmers come to town and set up outside the main entrance on the edge of the park. Really nice time to visit.
The Hotel is 156 rooms in a fairly recently renovated building with a new addition put on the top floors. Streets are narrow enough in Budapest that you can walk past buildings for years and never notice the vertical additions. They apparently removed all the architectural embellishments on the lower floors during the renovation, but still looks nice. This one is about 146 euro for as standard double in October. https://uphotelbudapest.com/
The lobby is really quite lovely and I suspect the rooms match what is in their website photos. Its a very nice place. But what really makes it work is the location. You are about 3 blocks from the House of Terror on one of the prettiest stretches of Andrassy ut. Being close to Andrassy ut means you can use the M1 to reach most of the sights in town, or make the walk, cause Andrassy ut is beautiful. The neighborhood is quiet, but you are close to Kiraly utca which takes you to the Deportation Ghetto. In the other direction on Kiraly utca you are not far from one of the best untouristed streets full of amazing architecture in town.
The biggest problem with the location is the side street comes out on to Andrassy ut between the M1 stations at the Oktogon (300m) and Vorosmarty tér (100m). But I could live with that.
And its close to two of my favorite restaurants Kiraly100 and Ferdinánd Monarchia Étterem
This is only a recommendation for the location,. Check the reviews and the prices they look very good on Booking.com and TA. I took some photographs. Didnt get any inside as those on the web page appeared to be accurate. https://1drv.ms/f/s!Ai7Zk-szxfTJi95Z5OQGEa_MgutWRA?e=HEnvaC
In the same general location is the Eurostars Ambassador which looks to have a few more amenities and might be a little less expensive and retains more of the old world charm on the outside.
