My husband and I travelled to Frankfurt from the UK and thoroughly enjoyed our stay in Adina Apartments Hotel. We stayed in a standard apartment which we found to be spacious, clean, quiet and superbly equipped. It really felt like a luxury stay helped by little touches such as a 'self defogging' bathroom mirror, a television with channels from a number of different countries, and the filter coffee/drinks options. A fine finish overall, top marks.
As for the area, it feels like a business area of the city with modern, tall buildings and a fabulous mall next door which includes a grocery store, pharmacy and many options to grab a quick lunch.
The train station and river Main is about a ten minute walk, be warned, you don't want to hang around the area immediately surrounding the train station especially at night as it feels very unsafe, but the Adina is a comfortable distance from this and you definitely notice the area change. We also walked to beautiful Römer which took about 30/40 minutes and the gardens/butterfly house which took about 25 minutes (7€ in an Uber back to Adina).
It cost 40€ in an airport taxi to get to the Adina but under €25 in an Uber to return from the Adina to the airport. (November 2023)
A free, secure baggage check is available if you want to get in some last minute exploring after checking out.
Overall a fantastic, modern base in Frankfurt and we will definitely book again if we return to Frankfurt.
