I stayed at Villa Serena for a month and I had a great time! Communication with Murad was very effective, check-in and check-out was very easy! The appartment is very well located, near 23rd avenue, which has a lot of restaurants, pubs and cafes. Grocery stores are very close too, and there is a bus stop 2 min from the appartment. The appartment was very clean, the bed is comfy, there is everything you need to cook basic stuff, although it would be nice to have a bit more cooking tools. Also, the wifi was not that reliable the time I was there, hopefully this will be fixed in the future!
Also, if you like hiking, Forest park is like a 10 min walk away from the appartment, and it is gorgeous!
