The apartment has a great potential, it is well kept and furnished, very nicely lit, beautiful view, excellent location for the old city.
But, and its a serious but - there are several extremly busy pubs downstairs that are super noisy till 2:00AM every night, and the isolation just does not work. We tried everything. So, bring earplugs if you plan to sleep at night. If you are hot and need to open the windows (no AC) - even earplugs will not do. What a shame for otherwise a lovely place.
Perhaps some people sleep so well no amount of noise keeps them up, but for us it was a major dent in a pleasurable holiday.
