It's in a really nice neighborhood to go for a walk. Joan was a great host.

I thought it was great. The house was built in 1910 and hills up really well.

La gentilezza e la disponibilità della proprietaria, che si è organizzata senza problemi per un late checkin autonomo (3 del mattino), e si è prodigata per accontentare le nostre richieste per la colazione

Camera molto "compatta", un po' stretta, ma nel complesso funzionale e accogliente

Stayed here for 1 night after a late flight and took a morning bus, but felt so refreshed and relaxed.
