LOVED IT! We spent three nights here in mid-September 2018 and loved it. We were a traveling family of 7, which was comprised of 6 girls and 1 boy including hubby and myself. With 6 girls we knew we needed plenty of bathrooms, and enough room to spread out. We got it at John's place.
The space was larger than photos even suggested, and there was plenty of space to spread out. The walls must be solid concrete, as you can't here anything as you sleep like a baby - no city noise, no noise from rooms on other side of walls, etc. It is a pretty apartment, although you can see where photos and belongings have been recently removed with the empty spots. But this in no way impared our visit. The balconies are so lovely, the experience in person is even better than the photos suggest.
The kitchen has plenty of counter space and we did plenty of meals and snacks at home. The living room is large, and we had enough seating for all of us although another couch or chair or two would have allowed a bit more room to lounge.
The location is excellent. It is a lovely area, and is busy but fun. Within two minutes walk you have multiple coffee cafes and the Fresh grocery store; you can get everything you need. Within same distance are several restaurants as well as a pharmacy. With a 7-10 minute walk you get to a bus stop that will do all the hop on/off buses as well as city buses, and taxis are also readily available.
The only concern we had was the hot water situation. One bathroom, the smallest bathroom, has an "instahot" so you don't run out of water and can get through the shower wonderfully. The other two bathrooms, which includes the master, appear to share a water supply and the hot water runs out fast. As in there is no time for washing your hair, just wash the body and hop out - ONCE, just one person. It is deceptive as there isn't enough to even take a bath in that gorgeous tub, you can fill it exactly 1/4 of the way up with warm bath water and then when you enter the tub it will rise to about 1/2 full... not exactly a luxurious bath. We ended up mostly bathing in the one bathroom closest to the living room except hubby, who being the only man could manage a two minute shower using that limited water supply in the master.
That said, we all know that as Americans we have an over inflated water use life style, and we love to bathe every day and sometimes twice, and traveling in Europe we can't expect the same situation. Unless you stay in some huge and expensive hotel you may find the exact same water limitations, so don't let it detract you from this place.
We would go back, quite happily!
