The apartment I stayed in was modern, clean, spacious with all the amenities needed. Contact was great, had a reception during morning to evening hours and then required code access to get in.
The apartment is in a quiet neighborhood but also 3 minutes away from a square that has cafés and bars on either side that are very popular in the evening. However it is around a 30 minute walk into the old town centre and public transport nearby other than taxi wouldn't make this quicker.
The only negative on the apartment for me was the Aircon it isn't very powerful, and it was quite warm to stay in, quite often warmer in the apartment than outside which unfortunately would have to avoid staying in during the hotter summer months
