For ~ 30 bucks a night, you can't really go wrong with Anna's place. The apartment is outside of Stockholm, but taking the metro is really convinient and only takes ~25 minutes to Gamla Stan. The apartment itself is okay for a short stay, since the neighbours are quite loud and noisy even past 10pm (we stayed 1 week).
Only thing that really bothered us is, that Anna didn't tell us about her brother Vlad staying with us in the apartment as well (she only mentioned, that he will be checking us in).
We don't know if that's always the case, but it was not communicated to us.
Usually we always go for female hosts, as we are anxious about male hosts (due to certain events that happened in other places).
Don't get us wrong, her brother was nice and helped us throughout our stay, but we wished that Anna mentioned it at least.
