Price is good, communication is perfect, check in easy. Mario is very reliable, answers quickly and helps with questions!
The bad part is: location in front of a very busy street and train very loud, if you are sensitive like me, you won't be able to sleep. Two things that could've been fixed bothered me: the sliding door to the bathroom was broken, very inconvenient if you are staying with a partner for example and need to go on the toilette and can't even close the door. The shower is not working properly, there comes nearly no water out of the shower head.
If noise doesn't bother you and you want a cheap stay, go for it, otherwise wouldn't recommend at all.
