We stayed at Alexandra's for one week. In our opinion, there are important pros and cons which need to be taken into consideration before choosing her flat.
Pros
The flat is very nice and big. We had everything (and more) that we could need. From dishwasher, all kitchen applies to a smart TV with Netflix for those moments when someone doesn't want to go out. There's no washing machine, but Alexandra offered to do the laundry for me at her house. The host is super nice and always ready to satisfy all of our needs; she even sent us a super long text suggesting different places we could visit (from restaurants, bars, museums to recreative places). The area is super close to the city center (2 bus stops with a stop at 100 m from the door).
Cons
The area is not super safe. One day we decided to take the metro instead of the bus and on our way there we found a street (super close to our flat) full of junkies and it was 10 in the morning. We saw many people using heavy drugs in the middle of the road. I know this doesn't depend on the host, but we think it could be useful to have infos about the streets to avoid, especially if they might be dangerous at all time. The small street in front of the flat is close to an old building which, because of an earthquake that happened 1 month ago, might lose some bricks every once in a while. The host literally told us "if you go through the street please do it fast".
I think this a nice place. We really enjoyed ourselves, but be sure to ask carefully the host which streets to avoid or maybe prefer the taxi instead of walking.
