Location puts you right in the heart of the old town, making it very easy to get anywhere in the city. The downside is that it's very busy, so you will be hearing quite a bit of street noise from tourists and musicians.
The apartment itself is cozy and meets all the needs for a typical stay. Biggest downside that I did not expect was the lack of high speed internet in the area. Typically would get about 2Mbit download, so I ended up using my mobile data for work.
