Sandra is a FABULOUS host! The apartment is lovely. She goes above and beyond expectations to provide useful info. Just one footnote: while the block her apartment is on is fairly nice, the neighborhood to the north, named "Lavapies" - may not be to everbody's taste. It is full of urban "grit" and home to quite a few unsavory characters. An urban bohemia is the best description. Urban dwellers and youth might find that environment stimulating...we found it a bit threatening at times.
This is just a caution for those like us. People who shun such environments can simply walk south instead, where a main street will take you anywhere in the city center by foot.
We overall had a wonderful stay. The apartment is a real gem.
