We stayed for two nights in April. We asked for a quiet room and were given room 402 - which was on the fourth floor and very quiet indeed. There is no lift so quite a way if you have lots of luggage. No street noise or anything else to disturb our sleep.
Reception staff were helpful and we were able to leave our luggage while we had breakfast before leaving to catch the bus to the Alpujarras.
The only problem was that the taxi driver (we arrived at the train station which is quite a way from the centre) did not know where the hostal was (a problem with street names being changed). But we were able to ring the hostal who gave the driver correct directions.
The Rough Guide does say that there is a restaurant, but this is only a bar and is two streets away.
There are many places to eat locally or nearer to the Alhambra and tourist areas.
Very good value and comfortable accommodation.
