The apartment is located in a nice area, about 20-30min by foot from the city center (or by bus). The area around the apartment has lots of restaurants, bars and shops and you‘ll probably find everything you need!
If you want to stay with Evelyn and Luis you should read their house rules but if you are fine with these it‘s a nice place for a city trip. The only thing to mention is that the walls are rather thin so you should make sure to talk quietly.
