What the trend suggests
Possible review removal2013-04 – 2016-0275% confidence
Massive 35-month gap with negligible rating change (4.0 → 4.17, delta +0.17). The near-zero delta, combined with complete absence of reviews across this entire period, is consistent with reviews being removed or suppressed rather than a genuine renovation-and-reopen cycle. Post-gap resumption shows typical operational ratings, not the uplift expected after closure + renovation.
Issue resolved2019-Q1 – 2026-Q380% confidence
Dated bathroom infrastructure was a recurring complaint in 2023 (Q1: 'Zimmer…hatte seine besten Tage hinter sich'; Q2: 'badkamer wel eens vernieuwd mag worden'). By 2025–2026, this complaint is entirely absent; instead, recent reviews consistently praise 'frisch renoviert' and 'very clean and spacious rooms…recently renovated' (2025-Q1, 2025-Q3), and 2026-Q2 highlights 'exceptional apartment.' This suggests bathroom and room renovation occurred between mid-2023 and early 2025.
Issue resolved2019-Q3 – 2023-Q472% confidence
Noise and traffic complaints appear in 2019-Q3 ('Struktur…direkt über der Rotonde…5 Uhr Verkehr') and 2023-Q3 ('recht laut'). However, by 2026-Q1 and 2026-Q2, location is praised as 'perfect,' 'quiet and comfortable,' and 'central yet quiet'—with no traffic or noise concerns mentioned. This reversal suggests either sound-dampening improvements or a shift in clientele perception post-renovation.
