Great location to visit the whole city, and although not the cleanest part of old town, at no point did we feel unsafe or did it really change anything, it was just an observation and really the only somewhat "negative" aspect (just to show you how little negative things there were to say about our stay).
Awesome hosts (very responsive, helpful, kind, and gave clear instructions on checking in and out), a modern apartment which is a little hidden away for extra privacy. All in all our experience was very positive, and I would definitely recommend it to anyone still hesitating.
