This is a lovely hotel in Madrid city center. 2 minutes (literally) from the Gran Via metro station. The booking was made via Otel.com. Stayed there for 8 days. Rooms were well sized and very clean. Bathroom also very spacious and clean. The bathroom had all kinds of personal amenities and kits (sewing, shaving etc). WiFi Internet worked as advertised and was completely free. Breakfast till 10:30 weekdays and 11:00 on weekends, which is great if you are on holidays and thus not an early riser. Staff is very friendly and helpful. Avoid rooms that have limited day light, due to the fact that they are in the back of the hotel. Great place if you want to explore Madrid.

All in all, a 4* experience for far less the amount of money requested by similar hotels nearby. Recommended.

Highly recommend Sieteislas due to its central location, modern décor and space.

We had a brilliant time in Madrid and can't wait to spend longer there, we went for 3 nights and 4 days and loved every minute the weather was very hot. Its a great City and we loved the Sangria and Tapas just what the doctor ordered for a weekend break away from work. The hotel is 4* however our room was a little dark because at the side of the building not much to look over but it was a comfortable room and had toilitries that were ideal.

When you eat out Tapas is great, however we found when we went for a drink in the bars they offered tapas either bread or olives one bar gave us pallea, so we didn't need to book a meal because we got fed with tapas every time.

There are quite a few sex shops however no one bothers you, so you don't notice it that much, and there is a lot of "ladies of the night" and same here they don't approach you, only if you want it you go to them so again no bother for us.

Great for shopping for bags and shoes 6 euros for a bag and 3 for a pair of sandals.

We completed our 10 day trip to Spain with 2 nights in Madrid and stayed at the Siete Islas Hotel. The location was very good. It is just off the Gran Via, a large boulevard near great restaurants, shopping, tour buses, city buses and Metro stop. We speak very little English but we were helped greatly by the front desk staff and were out touring in no time. We arrived in a rental car and quickly decided to turn the car in and use the city transportation. The parking in the historical part of the city is very limited and expensive. Although, if you have a car, there is a parking garage across the street from the hotel and another parking garage near the hotel that the hotel offers discounted parking rates. The Siete Islas is on a side street that felt a little "seedy" There is an adult [--] shop on the street and several hostals. We walked up and down the street at all hours and never felt unsafe.....it is the city and some of that is to be expected.
The hotel property is very well maintained and is clean and pleasantly decorated inside. The staff is very helpful. They offer free wireless internet throughout the hotel, even in the rooms. My husband had some trouble getting the internet started in our room but it was quickly straightened out with a visit to the front desk and a code that was needed to get it started. The room is not extra large but was adequate for our needs...the bathroom was nice and offered toiletries like shampoo, razor, soaps, lotions, etc. Hairdryer was in the bathroom as well. Free breakfast was included in the price of the room and it was a very nice surprise. As Americans, we are used to a nice breakfast to start the day and we had a very difficult time finding our kind of breakfast in Spain. Usually only croissants, toast, jelly and coffee...or should I say Espresso. But the breakfast offerd at the Siete Islas was wonderful! Bacon, sausage, eggs, cereal, toast, fruit, juices....on and on. Wonderful selection and all you cared to eat! Presented in a nice room with table cloths and flowers on the tables.
There is a computer in the main lobby of the hotel for the guests to use. It was very handy for checking emails and also printing boarding passes for our flight home. There is also a small cafe in the main lobby with limited offerings. The only negative that we might mention is the very limited selection of TV channels and no channels available in English. We were not in our room very much since we were there to see Madrid, but it would have been nice to see one news station that we could understand. They had several channels that offered movies for a fee.
Overall our visit to the Siete Islas was very nice and we would definitely return there if back in Madrid. The price was very good and the location and the value made the stay a pleasant experience.
