You have to love this place, because of it's extraordinary location. It is located in the (pedestrian) center of nice old city Umag, few meters from the sea, with great terrace where you will probably spend good part of your stay here, eating, looking to the sea, looking to crowd, enjoying sun, relaxing, enjoying evening. Apartment is literally surrounded by nice restaurants. Yet we don't find place too loud, it just gets quiet as the restaurants gets closed and then you can enjoy silence. Parking is generally a problem in Umag, but we have got parking card from our kind host Enzo, so we could park our car on public parking for free (blue parking lines). When you are coming to apartment, and you want to drive as close as you can to get the luggage out of the car, the best tip is to tuck your car to small parking near museum of Umag city, even if you don't find place you can leave your car there shortly to take luggage out of your car and then you have something like 150m to apartment.
You can not swim in the sea in front of apartment, you should go to some beach, best on north side of Umag. Beaches are not the strongest point of Istra, and bathing shoes are a must.
Apartment has nice and spacious sleeping room with double bed and window that looks to the sea - priceless. Small living room with one sofa (one can sleep there, maybe two) is just fine. Kitchen is small and modest but just good enough for breakfast etc. WiFi works fine. Apartment is not very modern and freshly renovated and equipped, but very charming and we loved it! From Umag, you can take excursions to whole Istra, and you can have very interesting vacation. We have stayed there beginning of june.
We would definitely like to come back.
