I can’t say enough good things about Aperon. The service is outstanding. They helped us with so many aspects of our trip and usually replied within 5 minutes! The location is so central yet it’s somehow quiet. The apartment is compact but has everything you need. It’s safe and efficient. We stayed in 2 units that were almost identical. They technically fit 4 but the sofa bed is a bit small and extremely hard so consider that if it might bother you. The only other potential downside is no elevator but everything else is just perfect.
