Make sure to arrange an exact arriving time because we had some trouble reaching Ellina at our arrival. But as soon as she saw our calls and texts she called us back and explained everything to us. For the rest of our trip she replied fast when we needed something. The mattress was pretty uncomfortable for us and it was cold in the apartment (difficult to heat up the place but we guess it's recommendable in summer). The location was very good, two tube stations were nearby.
