If you are planning to be out the whole time; then this is a great find. It's a large apartment, in a wonderful location.
Great shower. Very comfortable bed. Very little noise from neighbours. The windows open onto an internal shared space within building (not the street). Lots of space, and has a large kitchen table (perfect for eating or work).
I visited during the summer. It was 35 degrees outside, yet lovely and cool inside (it felt as low as 25 degrees). This made it very easy to sleep at night.
However it does have problems. Sadly it's not that well maintained. For example when I checked in, half the lights didn't work. Some that did were so dim, it was difficult to tell if they were on or off. This makes the place very gloomy.
The cleaning had only been superficial. There are lots of old dusty appliances left abandoned on the side of the kitchen, including a kittle covered in grime and hairs (which I didn't use it). Some furniture is broken (although most is fine). Sometimes the bathroom smells. Although the apartment isn't that bad.
The only real issue is the internet. It's borderline unusable.
It uses a 3G mobile signal for the Wifi router. This makes it very slow. I measured speeds from 1 to 3 mb/s. The connection is very inconsistent. For example the internet would often suddenly pause for 5 to 20 seconds, and do this as often as every few minutes. To put this into perspective; Spotify works, low quality YouTube works, Netflix can work (a bit). Video calls don't work. There were times I ended up just using my own phone for the internet. If you need to work whilst abroad; I would book somewhere else!
Otherwise it's a decent place. I would be happy to stay here again.
