I stayed at Serena's only for a weekend but it felt like home. Serena is very kind, friendly and welcoming. Since the first contact she made herself available to help us enjoy our stay. Our flying had a 2 hours day and we got lost on our way to the flat which meant she had to wait for us past midnight but still welcomed us with a warm smile.
The flat is big, bright and super clean. We felt very comfortable and we recommend it to everyone.
