Hello I thought I was going to Istanbul but our miles are taking us first class to Budapest and Vienna. We are going 4 days in buda then 3 in Vienna then 3 more buda want great hotel ideas in larger rooms near tourist stuff. My mother is older and will not do subways (if they have them) or steep stairs. Ideas on where to stay-would like to try 2 different hotels in Budapest would like 4 to 5 star hotels please. We are going during Easter time.
