We had almost two days where we didn't leave the room for our 5/6 day trip. We enjoyed it that much.
I did have a few groceries delivered and picked them up in the lobby and I know general food delivery was an option as well.
If you plan on staying for more than a few days and will be out and about and busy, I would suggest spending extra on cleaning services (but then again I'm pretty lazy).
I loved the customer service by Tower Signature staff. We were early (by hours) when we went to leave luggage but staff made sure we were pre-checked in making sure all we needed to do was pick up a key when we returned. We left to meet up with our daughter and it was no more than an hour later than we received a call from the gentleman that 'pre-checked' us in letting us know the room was ready. He had not promised a phone call and had no obligation but it was so kind.
Shelly and staff have been great, communicative and helpful. Even when I had a question six months ago. Everything was much appreciated.
