Are you looking for a room in Cardiff? I have just renovated and extended my mid-terraced house in Cathays (near the city centre) and it now has more rooms than I use. It has many low energy and labour saving devices. A well equipped and spacious kitchen/dinning room, which looks onto the garden (a work in progress). Close to the shops, parks, sports facilities and pool. Only a short walk to cinema, theatre, libraries and university. The busses run past the end of the street, It's five minutes walk to the train and a few miles to the motorway It is ideal for a student or professional wishing to stay near the centre.
In short it's all you need. And no agency fees.
