I had a wonderful stay in Sevilla at casa de Manuel. It is a spacious appartment with a balcony (next to the living room) where I had my breakfast every day. The bedroom is clean and good and you have a private bathroom. He also just did a renovation on the windows so isolation from the heat and city-sounds is very good. The location is great, close to shopping aerea, cathedral and other site-seeing places, and also close to Triana (also very nice neighbourhood) and the Plaza the Armas where the busterminal is (a.o. bus to airport and other destinations in Spain).
Manuel is a very friendly and social host who helped me with everything I needed and showed me good places in the city (the best tapas!) And every spare time he has he spends it on learning English, which is going very well! And if you want to learn Spanish it's a good way to exchange.
Manuel thanks for all and good luck with your exams!
