Serena was a great host. We ended up arriving an hour later than planned, but Serena was still waiting for us when we arrived. She gave us a tour of the apartment and had even drawn a map for us showing us the location of restaurants and grocery stores nearby.
At one point there were 11 of us in the apartment and the living room was big enough to hold all of us. This is a great place for larger groups.
The place was as described and the many large bedrooms made it possible to configure the sleeping arrangements.
We were within a 20 minute walk to Saint Peters and there were plenty of little cafe's in the neighborhood.
