0.6km from Le , Viet Thai SushiThe Riu Plaza is a 4-star place owned by the Spanish Riu chain, obviously aimed primarily at business and conference people. But it's a good place to stay for holidaymakers too. - Very well located in Schöneberg, 150 metres from Wittenbergplatz (and a little further to Nollendorfplatz in the other direction), so pretty easy access on the U-bahn to almost everywhere, and only 1 stop from Zoo Garden terminal for airport buses. - large, airy rooms, with good views (we were on 16th floor), comfortable bed, excellent and spacious shower and good bathroom in general, fast lifts - a good bar, with friendly bar and wait staff, and not overpriced, just off the reception desk area - generally friendly and efficient front desk staff (but see further on) - not expensive, at least in winter; we paid only just over 100 euros a night, which is good value Its flaws are minimal, but...: - Breakfast is too expensive. Sure, it has all the usual breakfast buffet stuff, but it significantly adds to the cost of the holiday to cough up 19 euros pp each day (we stayed 4 nights). Having just come from an excellent central hotel in Lisbon, where we had an excellent breakfast for 12 euros pp each morning, it seemed excessive, so we settled for a nearby cafe each day. - Make sure you put the 'do not disturb' sign on your door each day if you don't want to get up early. The first day we were there, Monday, having arrived in Berlin at half past midnight, we were woken up at 8.45 am by a cleaner banging on the door. Happened again at the same time a couple of days later when we forgot to put the sign out. Sorry, when you're staying for 4 days, there's no reason to clean the room that early - and I blame the management, not the cleaners, who just do what they're told. - Some of the staff are a little slapdash. E.g., the kettle in our room had been ruined by an idiot previous occupant trying to use it as a coffee perculator, so there was a baked-on layer of coffee on the bottom of it. On our way out the next morning, we took it down to the front desk - the guy there actually asked us to take it back up to our room on the 16th floor, and assured us it would be replaced by the cleaners. When we returned from sightseeing 6 hours later, guess what - the ruined kettle was still there in our room. Fail! I know this is a 1st-world problem, but the original front desk guy should have just taken the kettle and organised to get it replaced. When we took it down again, this time the woman on the front desk took it from us, and a short time later a new kettle was in our room. I don't want to criticise the place too much, as it was pretty good overall and we'd stay there again. But it felt a little impersonal, and while most of the staff were excellent, some were not well-trained or motivated enough to deal properly with issues, relatively minor though our's were. Thus, it gets 4 stars, not 5.
