We stayed for four nights with a family of four (two adults + two teens). Overall the apartment is excellent!
Biggest selling points in my opinion are the location and free parking. The apartment is located along a very quiet lane so nights are peaceful even with the windows open. Free parking is around the corner and very straightforward. Oh and the Wifi is really fast (~80/40 Mbps). Shops and restaurants nearby and getting to Old Town is really 10 mins.
Possible reasons not to rent? Well, the apartment might be pretty hot during really hot days (but you will not be staying indoors anyway, right?). The airconditioning in the apartment is very basic, so don't expect miracles from it. Best way to cool down the apartment for the nights is to open the windows on the roof. This cools down the rooms nicely. Minor annoyance is the possibility of mosquitos. We had some coming in through the open windows at night, which can be slightly annoying, but not dangerous.
