They are "old" and "new" buildings like you would think in normal cases. The orginal building of TTR is building 2 that surrounds the PadyO bar and one of the most sought after places to stay. All the buildings have been renovated so you won't find any indications that way. Jamie
We stayed in building 2 last year. The rooms were nice there are some signs of poor craftsmanship and some spots needing repair. But nothing the took away from the overall nice surroundings I guess f you are looking for it you will find some things but nothing I haven't seen at any other hotel. Be careful though as it can be VERY slippery walling through the patio area.
