If you are planning to stay at a spa hotel, I recommend not going either to the hotel "Meri" nor to "Rüütli". The water in the pool of the hotel "Rüütli" was unclean and the sauna was not working. The jacuzzi was not working either - it just had still water in it. The hotel did not provide separate towels for visiting spa other than the towels provided to the hotel room. The choice of food during breakfast was very poor, the machine coffee tasted terrible and when asked from the staff whether they are serving cappuccinos, they said that was unavailable before 11 am.
The location is excellent, although the hotel next door was better hotel, Georg Ots Spa. It is an average 3-star hotel, although the staff is wonderful.
