I would rate as a 7 out of 10.
Incredible location that made it easy to see many of the sites by walking and apartment was clean; plenty of linens. WiFi worked well. Noise level was very calm.
Main mattress was a bit worn and one of the pull-outs was broken but rigged to work (host called us and informed of this before we arrived so I’m not knocking any points off for that). Pull-outs were comfortable for the kids but only one of the two would be suitable for an adult(s); the other was quite thin, maybe 3” thick. We also had an issue with the washing machine which messed with our packing plans slightly (had to hand wash some items).
Overall, everything worked OK for our short (4 nights) trip and, for the price I would rate as a good value.
